+# Chai Contribution Guidelines
+
+We like to encourage you to contribute to the Chai.js repository. This should be as easy as possible for you but there are a few things to consider when contributing. The following guidelines for contribution should be followed if you want to submit a pull request or open an issue.
+
+Following these guidelines helps to communicate that you respect the time of the developers managing and developing this open source project. In return, they should reciprocate that respect in addressing your issue or assessing patches and features.
+
+#### Table of Contents
+
+- [TLDR;](#tldr)
+- [Contributing](#contributing)
+ - [Bug Reports](#bugs)
+ - [Feature Requests](#features)
+ - [Pull Requests](#pull-requests)
+- [Releasing](#releasing)
+- [Support](#support)
+ - [Resources](#resources)
+ - [Core Contributors](#contributors)
+
+
+## TLDR;
+
+- Creating an Issue or Pull Request requires a [GitHub](http://github.com) account.
+- Issue reports should be **clear**, **concise** and **reproducible**. Check to see if your issue has already been resolved in the [master]() branch or already reported in Chai's [GitHub Issue Tracker](https://github.com/chaijs/chai/issues).
+- Pull Requests must adhere to strict [coding style guidelines](https://github.com/chaijs/chai/wiki/Chai-Coding-Style-Guide).
+- In general, avoid submitting PRs for new Assertions without asking core contributors first. More than likely it would be better implemented as a plugin.
+- Additional support is available via the [Google Group](http://groups.google.com/group/chaijs) or on irc.freenode.net#chaijs.
+- **IMPORTANT**: By submitting a patch, you agree to allow the project owner to license your work under the same license as that used by the project.
+
+
+
+
+## Contributing
+
+The issue tracker is the preferred channel for [bug reports](#bugs),
+[feature requests](#features) and [submitting pull
+requests](#pull-requests), but please respect the following restrictions:
+
+* Please **do not** use the issue tracker for personal support requests (use
+ [Google Group](https://groups.google.com/forum/#!forum/chaijs) or IRC).
+* Please **do not** derail or troll issues. Keep the discussion on topic and
+ respect the opinions of others
+
+
+### Bug Reports
+
+A bug is a **demonstrable problem** that is caused by the code in the repository.
+
+Guidelines for bug reports:
+
+1. **Use the GitHub issue search** — check if the issue has already been reported.
+2. **Check if the issue has been fixed** — try to reproduce it using the latest `master` or development branch in the repository.
+3. **Isolate the problem** — create a test case to demonstrate your issue. Provide either a repo, gist, or code sample to demonstrate you problem.
+
+A good bug report shouldn't leave others needing to chase you up for more information. Please try to be as detailed as possible in your report. What is your environment? What steps will reproduce the issue? What browser(s) and/or Node.js versions experience the problem? What would you expect to be the outcome? All these details will help people to fix any potential bugs.
+
+Example:
+
+> Short and descriptive example bug report title
+>
+> A summary of the issue and the browser/OS environment in which it occurs. If suitable, include the steps required to reproduce the bug.
+>
+> 1. This is the first step
+> 2. This is the second step
+> 3. Further steps, etc.
+>
+> `` - a link to the reduced test case OR
+> ```js
+> expect(a).to.equal('a');
+> // code sample
+> ```
+>
+> Any other information you want to share that is relevant to the issue being reported. This might include the lines of code that you have identified as causing the bug, and potential solutions (and your opinions on their merits).
+
+
+### Feature Requests
+
+Feature requests are welcome. But take a moment to find out whether your idea fits with the scope and aims of the project. It's up to *you* to make a strong case to convince the project's developers of the merits of this feature. Please provide as much detail and context as possible.
+
+Furthermore, since Chai.js has a [robust plugin API](http://chaijs.com/guide/plugins/), we encourage you to publish **new Assertions** as plugins. If your feature is an enhancement to an **existing Assertion**, please propose your changes as an issue prior to opening a pull request. If the core Chai.js contributors feel your plugin would be better suited as a core assertion, they will invite you to open a PR in [chaijs/chai](https://github.com/chaijs/chai).
+
+
+### Pull Requests
+
+- PRs for new core-assertions are advised against.
+- PRs for core-assertion bug fixes are always welcome.
+- PRs for enhancing the interfaces are always welcome.
+- PRs that increase test coverage are always welcome.
+- PRs are scrutinized for coding-style.
+
+Good pull requests - patches, improvements, new features - are a fantastic help. They should remain focused in scope and avoid containing unrelated commits.
+
+**Please ask first** before embarking on any significant pull request (e.g. implementing features, refactoring code), otherwise you risk spending a lot of time working on something that the project's developers might not want to merge into the project.
+
+Please adhere to the coding conventions used throughout a project (indentation, accurate comments, etc.) and any other requirements (such as test coverage). Please review the [Chai.js Coding Style Guide](https://github.com/chaijs/chai/wiki/Chai-Coding-Style-Guide).
+
+Follow this process if you'd like your work considered for inclusion in the project:
+
+1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork, and configure the remotes:
+
+```bash
+# Clone your fork of the repo into the current directory
+git clone https://github.com//
+# Navigate to the newly cloned directory
+cd
+# Assign the original repo to a remote called "upstream"
+git remote add upstream https://github.com//
+```
+
+2. If you cloned a while ago, get the latest changes from upstream:
+
+```bash
+git checkout
+git pull upstream
+```
+
+3. Create a new topic branch (off the main project development branch) to contain your feature, change, or fix:
+
+```bash
+git checkout -b
+```
+
+4. Commit your changes in logical chunks. Use Git's [interactive rebase](https://help.github.com/articles/interactive-rebase) feature to tidy up your commits before making them public.
+
+5. Locally merge (or rebase) the upstream development branch into your topic branch:
+
+```bash
+git pull [--rebase] upstream
+```
+
+6. Push your topic branch up to your fork:
+
+```bash
+git push origin
+```
+
+7. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/) with a clear title and description.
+
+**IMPORTANT**: By submitting a patch, you agree to allow the project owner to license your work under the same license as that used by the project.
+
+
+## Releasing
+
+Releases can be **prepared** by anyone with access to the code.
+
+Simply run `make release-major`, `make release-minor`, or `make-release-patch`
+and it will automatically do the following:
+
+ - Build chai.js
+ - Bump the version numbers accross the project
+ - Make a commit within git
+
+All you need to do is push the commit up and make a pull request, one of the core contributors will merge it and publish a release.
+
+### Publishing a Release
+
+Anyone who is a core contributor (see the [Core Contributors Heading in the Readme](https://github.com/chaijs/chai#core-contributors)) can publish a release:
+
+1. Go to te [Releases page on Github](https://github.com/chaijs/chai/releases)
+2. Hit "Draft a new release" (if you can't see this, you're not a core contributor!)
+3. Write human-friendly Release Notes based on changelog.
+ - The release title is "x.x.x / YYYY-MM-DD" (where x.x.x is the version number)
+ - If breaking changes, write migration tutorial(s) and reasoning.
+ - Callouts for community contributions (PRs) with links to PR and contributing user.
+ - Callouts for other fixes made by core contributors with links to issue.
+4. Hit "Save Draft" and get other core contributors to check your work, or alternatively hit "Publish release"
+5. That's it!
+

+## 1.10.0 / 2014-11-10
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+ - No changes required
+- **Plugin Developers:**
+ - Review `addChainableNoop` notes below.
+- **Core Contributors:**
+ - Refresh `node_modules` folder for updated dependencies.
+
+### Noop Function for Terminating Assertion Properties
+
+The following assertions can now also be used in the function-call form:
+
+* ok
+* true
+* false
+* null
+* undefined
+* exist
+* empty
+* arguments
+* Arguments
+
+The above list of assertions are property getters that assert immediately on
+access. Because of that, they were written to be used by terminating the assertion
+chain with a property access.
+
+```js
+expect(true).to.be.true;
+foo.should.be.ok;
+```
+
+This syntax is definitely aesthetically pleasing but, if you are linting your
+test code, your linter will complain with an error something like "Expected an
+assignment or function call and instead saw an expression." Since the linter
+doesn't know about the property getter it assumes this line has no side-effects,
+and throws a warning in case you made a mistake.
+
+Squelching these errors is not a good solution as test code is getting to be
+just as important as, if not more than, production code. Catching syntactical
+errors in tests using static analysis is a great tool to help make sure that your
+tests are well-defined and free of typos.
+
+A better option was to provide a function-call form for these assertions so that
+the code's intent is more clear and the linters stop complaining about something
+looking off. This form is added in addition to the existing property access form
+and does not impact existing test code.
+
+```js
+expect(true).to.be.true();
+foo.should.be.ok();
+```
+
+These forms can also be mixed in any way, these are all functionally identical:
+
+```js
+expect(true).to.be.true.and.not.false();
+expect(true).to.be.true().and.not.false;
+expect(true).to.be.true.and.not.false;
+```
+
+#### Plugin Authors
+
+If you would like to provide this function-call form for your terminating assertion
+properties, there is a new function to register these types of asserts. Instead
+of using `addProperty` to register terminating assertions, simply use `addChainableNoop`
+instead; the arguments to both are identical. The latter will make the assertion
+available in both the attribute and function-call forms and should have no impact
+on existing users of your plugin.

+
+## 1.9.1 / 2014-03-19
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+ - Migrate configuration options to new interface. (see notes)
+- **Plugin Developers:**
+ - No changes required
+- **Core Contributors:**
+ - Refresh `node_modules` folder for updated dependencies.
+
+### Configuration
+
+There have been requests for changes and additions to the configuration mechanisms
+and their impact in the Chai architecture. As such, we have decoupled the
+configuration from the `Assertion` constructor. This not only allows for centralized
+configuration, but will allow us to shift the responsibility from the `Assertion`
+constructor to the `assert` interface in future releases.
+
+These changes have been implemented in a non-breaking way, but a depretiation
+warning will be presented to users until they migrate. The old config method will
+be removed in either `v1.11.0` or `v2.0.0`, whichever comes first.
+
+#### Quick Migration
+
+```js
+// change this:
+chai.Assertion.includeStack = true;
+chai.Assertion.showDiff = false;
+
+// ... to this:
+chai.config.includeStack = true;
+chai.config.showDiff = false;
+```
+
+#### All Config Options
+
+##### config.includeStack
+
+- **@param** _{Boolean}_
+- **@default** `false`
+
+User configurable property, influences whether stack trace is included in
+Assertion error message. Default of `false` suppresses stack trace in the error
+message.
+
+##### config.showDiff
+
+- **@param** _{Boolean}_
+- **@default** `true`
+
+User configurable property, influences whether or not the `showDiff` flag
+should be included in the thrown AssertionErrors. `false` will always be `false`;
+`true` will be true when the assertion has requested a diff be shown.
+
+##### config.truncateThreshold **(NEW)**
+
+- **@param** _{Number}_
+- **@default** `40`
+
+User configurable property, sets length threshold for actual and expected values
+in assertion errors. If this threshold is exceeded, the value is truncated.
+
+Set it to zero if you want to disable truncating altogether.
+
+```js
+chai.config.truncateThreshold = 0; // disable truncating
+```

+This is a small patch that updates the dependency tree so browserify users can install
+chai. (Remove conditional requires)
+
+## 1.8.0 / 2013-09-18
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+ - See `deep.equal` notes.
+- **Plugin Developers:**
+ - No changes required
+- **Core Contributors:**
+ - Refresh `node_modules` folder for updated dependencies.
+
+### Deep Equals
+
+This version of Chai focused on a overhaul to the deep equal utility. The code for this
+tool has been removed from the core lib and can now be found at:
+[chai / deep-eql](https://github.com/chaijs/deep-eql). As stated in previous releases,
+this is part of a larger initiative to provide transparency, independent testing, and coverage for
+some of the more complicated internal tools.
+
+For the most part `.deep.equal` will behave the same as it has. However, in order to provide a
+consistent ruleset across all types being tested, the following changes have been made and _might_
+require changes to your tests.
+
+**1.** Strict equality for non-traversable nodes according to [egal](http://wiki.ecmascript.org/doku.php?id=harmony:egal).
+
+_Previously:_ Non-traversable equal via `===`.
+
+```js
+expect(NaN).to.deep.equal(NaN);
+expect(-0).to.not.deep.equal(+0);
+```
+
+**2.** Arguments are not Arrays (and all types must be equal):
+
+_Previously:_ Some crazy nonsense that led to empty arrays deep equaling empty objects deep equaling dates.
+
+```js
+expect(arguments).to.not.deep.equal([]);
+expect(Array.prototype.slice.call(arguments)).to.deep.equal([]);
+```
+
+- [#156](https://github.com/chaijs/chai/issues/156) Empty object is eql to empty array
+- [#192](https://github.com/chaijs/chai/issues/192) empty object is eql to a Date object
+- [#194](https://github.com/chaijs/chai/issues/194) refactor deep-equal utility
+
+### CI and Browser Testing
+
+Chai now runs the browser CI suite using [Karma](http://karma-runner.github.io/) directed at
+[SauceLabs](https://saucelabs.com/). This means we get to know where our browser support stands...
+and we get a cool badge:
+
+[](https://saucelabs.com/u/logicalparadox)
+
+Look for the list of browsers/versions to expand over the coming releases.
+
+- [#195](https://github.com/chaijs/chai/issues/195) karma test framework
+
+## 1.7.2 / 2013-06-27
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+ - No changes required.
+- **Plugin Developers:**
+ - No changes required
+- **Core Contributors:**
+ - Refresh `node_modules` folder for updated dependencies.
+
+### Coverage Reporting
+
+Coverage reporting has always been available for core-developers but the data has never been published
+for our end users. In our ongoing effort to improve accountability this data will now be published via
+the [coveralls.io](https://coveralls.io/) service. A badge has been added to the README and the full report
+can be viewed online at the [chai coveralls project](https://coveralls.io/r/chaijs/chai). Furthermore, PRs
+will receive automated messages indicating how their PR impacts test coverage. This service is tied to TravisCI.
+
+### Other Fixes
+
+- [#175](https://github.com/chaijs/chai/issues/175) Add `bower.json`. (Fix ignore all)
+
+## 1.7.1 / 2013-06-24
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+ - No changes required.
+- **Plugin Developers:**
+ - No changes required
+- **Core Contributors:**
+ - Refresh `node_modules` folder for updated dependencies.
+
+### Official Bower Support
+
+Support has been added for the Bower Package Manager ([bower.io])(http://bower.io/). Though
+Chai could be installed via Bower in the past, this update adds official support via the `bower.json`
+specification file.
+
+- [#175](https://github.com/chaijs/chai/issues/175) Add `bower.json`.
+
+## 1.7.0 / 2013-06-17
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+ - No changes required.
+- **Plugin Developers:**
+ - Review AssertionError update notice.
+- **Core Contributors:**
+ - Refresh `node_modules` folder for updated dependencies.
+
+### AssertionError Update Notice
+
+Chai now uses [chaijs/assertion-error](https://github.com/chaijs/assertion-error) instead an internal
+constructor. This will allow for further iteration/experimentation of the AssertionError constructor
+independant of Chai. Future plans include stack parsing for callsite support.
+
+This update constructor has a different constructor param signature that conforms more with the standard
+`Error` object. If your plugin throws and `AssertionError` directly you will need to update your plugin
+with the new signature.
+
+```js
+var AssertionError = require('chai').AssertionError;
+
+/**
+ * previous
+ *
+ * @param {Object} options
+ */
+
+throw new AssertionError({
+ message: 'An assertion error occurred'
+ , actual: actual
+ , expect: expect
+ , startStackFunction: arguments.callee
+ , showStack: true
+});
+
+/**
+ * new
+ *
+ * @param {String} message
+ * @param {Object} options
+ * @param {Function} start stack function
+ */
+
+throw new AssertionError('An assertion error occurred', {
+ actual: actual
+ , expect: expect
+ , showStack: true
+}, arguments.callee);
+
+// other signatures
+throw new AssertionError('An assertion error occurred');
+throw new AssertionError('An assertion error occurred', null, arguments.callee);
+```
+
+#### External Dependencies
+
+This is the first non-developement dependency for Chai. As Chai continues to evolve we will begin adding
+more; the next will likely be improved type detection and deep equality. With Chai's userbase continually growing
+there is an higher need for accountability and documentation. External dependencies will allow us to iterate and
+test on features independent from our interfaces.
+
+Note: The browser packaged version `chai.js` will ALWAYS contain all dependencies needed to run Chai.

+
+### New Assertions
+
+#### Array Members Inclusion
+
+Asserts that the target is a superset of `set`, or that the target and `set` have the same members.
+Order is not taken into account. Thanks to [@NickHeiner](https://github.com/NickHeiner) for the contribution.
+
+```js
+// (expect/should) full set
+expect([4, 2]).to.have.members([2, 4]);
+expect([5, 2]).to.not.have.members([5, 2, 1]);
+
+// (expect/should) inclusion
+expect([1, 2, 3]).to.include.members([3, 2]);
+expect([1, 2, 3]).to.not.include.members([3, 2, 8]);
+
+// (assert) full set
+assert.sameMembers([ 1, 2, 3 ], [ 2, 1, 3 ], 'same members');
+
+// (assert) inclusion
+assert.includeMembers([ 1, 2, 3 ], [ 2, 1 ], 'include members');
+
+```
+
+#### Non-inclusion for Assert Interface
+
+Most `assert` functions have a negative version, like `instanceOf()` has a corresponding `notInstaceOf()`.
+However `include()` did not have a corresponding `notInclude()`. This has been added.
+
+```js
+assert.notInclude([ 1, 2, 3 ], 8);
+assert.notInclude('foobar', 'baz');
+```
+
+### Community Contributions

+
+Thank you to all who took time to contribute!
+
+### Other Bug Fixes
+
+- [#142](https://github.com/chaijs/chai/issues/142) `assert#include` will no longer silently pass on wrong-type haystack.
+- [#158](https://github.com/chaijs/chai/issues/158) `assert#notInclude` has been added.
+- Travis-CI now tests Node.js `v0.10.x`. Support for `v0.6.x` has been removed. `v0.8.x` is still tested as before.
+
+## 1.5.0 / 2013-02-03
+
+### Migration Requirements
+
+The following changes are required if you are upgrading from the previous version:
+
+- **Users:**
+ - _Update [2013-02-04]:_ Some users may notice a small subset of deep equality assertions will no longer pass. This is the result of
+ [#120](https://github.com/chaijs/chai/issues/120), an improvement to our deep equality algorithm. Users will need to revise their assertions
+ to be more granular should this occur. Further information: [#139](https://github.com/chaijs/chai/issues/139).
+- **Plugin Developers:**
+ - No changes required.
+- **Core Contributors:**
+ - Refresh `node_modules` folder for updated developement dependencies.

+
+
+### Usage Updates
+
+#### For Users
+
+**1. Component Support:** Chai now included the proper configuration to be installed as a
+[component](https://github.com/component/component). Component users are encouraged to consult
+[chaijs.com](http://chaijs.com) for the latest version number as using the master branch
+does not gaurantee stability.
+
+```js
+// relevant component.json
+ devDependencies: {
+ "chaijs/chai": "1.5.0"
+ }
+```
+
+Alternatively, bleeding-edge is available:
+
+ $ component install chaijs/chai
+
+**2. Configurable showDiff:** Some test runners (such as [mocha](http://visionmedia.github.com/mocha/))
+include support for showing the diff of strings and objects when an equality error occurs. Chai has
+already included support for this, however some users may not prefer this display behavior. To revert to
+no diff display, the following configuration is available:
+
+```js
+chai.Assertion.showDiff = false; // diff output disabled
+chai.Assertion.showDiff = true; // default, diff output enabled
+```
+
+#### For Plugin Developers
+
+**1. New Utility - type**: The new utility `.type()` is available as a better implementation of `typeof`
+that can be used cross-browser. It handles the inconsistencies of Array, `null`, and `undefined` detection.
+
+- **@param** _{Mixed}_ object to detect type of
+- **@return** _{String}_ object type
+
+```js
+chai.use(function (c, utils) {
+ // some examples
+ utils.type({}); // 'object'
+ utils.type(null); // `null'
+ utils.type(undefined); // `undefined`
+ utils.type([]); // `array`
+});
+```
+
+#### For Core Contributors
+
+**1. Browser Testing**: Browser testing of the `./chai.js` file is now available in the command line
+via PhantomJS. `make test` and Travis-CI will now also rebuild and test `./chai.js`. Consequently, all
+pull requests will now be browser tested in this way.
+
+_Note: Contributors opening pull requests should still NOT include the browser build._
+
+**2. SauceLabs Testing**: Early SauceLab support has been enabled with the file `./support/mocha-cloud.js`.
+Those interested in trying it out should create a free [Open Sauce](https://saucelabs.com/signup/plan) account
+and include their credentials in `./test/auth/sauce.json`.

+
+> Improved deep equality testing for Node.js and the browser.
+
+## Installation
+
+### Node.js
+
+`deep-eql` is available on [npm](http://npmjs.org).
+
+ $ npm install deep-eql
+
+### Component
+
+`deep-eql` is available as a [component](https://github.com/component/component).

+
+## Usage
+
+### Rules
+
+- Strict equality for non-traversable nodes according to [egal](http://wiki.ecmascript.org/doku.php?id=harmony:egal).
+ - `eql(NaN, NaN).should.be.true;`
+ - `eql(-0, +0).should.be.false;`
+- Arguments are not Arrays:
+ - `eql([], arguments).should.be.false;`
+ - `eql([], Array.prototype.slice.call(arguments)).should.be.true;`

+# type-detect [](https://travis-ci.org/chaijs/type-detect) [](https://coveralls.io/r/chaijs/type-detect?branch=master)
+
+> Improved typeof detection for node.js and the browser.
+
+## Installation
+
+### Node.js
+
+`type-detect` is available on [npm](http://npmjs.org).
+
+ $ npm install type-detect
+
+### Component
+
+`type-detect` is available as a [component](https://github.com/component/component).
+
+ $ component install chaijs/type-detect
+
+## Usage
+
+### Primary
+
+The primary export of `type-detect` is function that can server as a replacement for
+`typeof`. The results of this function will be more specific than that of native `typeof`.
+
+```js
+var type = require('type-detect');
+```
+
+#### array
+
+```js
+assert('array' === type([]));
+assert('array' === type(new Array()));
+```
+
+#### regexp
+
+```js
+assert('regexp' === type(/a-z/gi));
+assert('regexp' === type(new RegExp('a-z')));
+```
+
+#### function
+
+```js
+assert('function' === type(function () {}));
+```
+
+#### arguments
+
+```js
+(function () {
+ assert('arguments' === type(arguments));
+})();
+```
+
+#### date
+
+```js
+assert('date' === type(new Date));
+```
+
+#### number
+
+```js
+assert('number' === type(1));
+assert('number' === type(1.234));
+assert('number' === type(-1));
+assert('number' === type(-1.234));
+assert('number' === type(Infinity));
+assert('number' === type(NaN));
+```
+
+#### string
+
+```js
+assert('string' === type('hello world'));
+```
+
+#### null
+
+```js
+assert('null' === type(null));
+assert('null' !== type(undefined));
+```
+
+#### undefined
+
+```js
+assert('undefined' === type(undefined));
+assert('undefined' !== type(null));
+```
+
+#### object
+
+```js
+var Noop = function () {};
+assert('object' === type({}));
+assert('object' !== type(Noop));
+assert('object' === type(new Noop));
+assert('object' === type(new Object));
+assert('object' === type(new String('hello')));
+```
+
+### Library
+
+A `Library` is a small constructed repository for custom type detections.
+
+```js
+var lib = new type.Library;
+```
+
+#### .of (obj)
+
+* **@param** _{Mixed}_ object to test
+* **@return** _{String}_ type
+
+Expose replacement `typeof` detection to the library.
+
+```js
+if ('string' === lib.of('hello world')) {
+ // ...
+}
+```
+
+
+#### .define (type, test)
+
+* **@param** _{String}_ type
+* **@param** _{RegExp|Function}_ test
+
+Add a test to for the `.test()` assertion.
+
+Can be defined as a regular expression:
+
+```js
+lib.define('int', /^[0-9]+$/);
+```
+
+... or as a function:
+
+```js
+lib.define('bln', function (obj) {
+ if ('boolean' === lib.of(obj)) return true;
+ var blns = [ 'yes', 'no', 'true', 'false', 1, 0 ];
+ if ('string' === lib.of(obj)) obj = obj.toLowerCase();
+ return !! ~blns.indexOf(obj);
+});
+```
+
+
+#### .test (obj, test)
+
+* **@param** _{Mixed}_ object
+* **@param** _{String}_ type
+* **@return** _{Boolean}_ result
+
+Assert that an object is of type. Will first
+check natives, and if that does not pass it will
+use the user defined custom tests.
+
+```js
+assert(lib.test('1', 'int'));
+assert(lib.test('yes', 'bln'));
+```

+ * travis: allow for tagged releases to npm
+ * docs: new string is type string, not object
+ * Merge pull request #5 from Charminbear/string-object-as-string
+ * Also updated the Docs with new Spec.
+ * Made "new String()" return type "string" instead of object and added test for "new Number()"
+ * Merge pull request #4 from Charminbear/include-ecma6-types

+ * Added 'else' statement to tests make skipping visual.
+ * Implemented furthert support for promises.
+ * Merge remote-tracking branch 'origin/include-ecma6-types' into include-ecma6-types
+ * Changed the getType() Method to be more generic and support ECMA6 as well as custom types Deleted NativeTypes as no longer needed Added (fake) Tests for ECMA6 types (by stubbing Object.prototype.toString) Updated Readme.md with ECMA6 Types
+ * Implemented conditional tests for ECMA6 features with real types.
+ * Moved regex into variable.
+ * Flipped assert statements.
+ * Added ArrayBuffer in description
+ * Fixed spell mistake.
+ * Merge branch 'include-ecma6-types' of https://github.com/Charminbear/type-detect into include-ecma6-types
+ * Added a description for Symbol.toStringTag
+ * Added a description for Symbol.toStringTag
+ * Fixed some formatting issues
+ * Added a test for ArrayBuffer.
+ * Added the new ECMA 6 Types to description.
+ * Renamed "stubToStringMethod" to "stubObjectToStringOnce" to make purpose more clear.
+ * Made stub of Object.prototype.toString restore itself on call as Mocha uses this method after tests.
+ * Changed getType() Method to be more generic for every given type, but still respect new String() and special PhantomJS Values.
+ * Added new types simple and implemented tests with stubbing "Object.prototype.toString"

+assert(type({}) === 'object');
+assert(type(Noop) !== 'object');
+assert(type(new Noop) === 'object');
+assert(type(new Object) === 'object');
+```
+
+#### ECMA6 Types
+
+Supports all ECMA6 Types:
+
+```js
+assert(type(new Map() === 'map');
+assert(type(new WeakMap()) === 'weakmap');
+assert(type(new Set()) === 'set');
+assert(type(new WeakSet()) === 'weakset');
+assert(type(Symbol()) === 'symbol');
+assert(type(new Promise(callback) === 'promise');
+assert(type(new Int8Array()) === 'int8array');
+assert(type(new Uint8Array()) === 'uint8array');
+assert(type(new UInt8ClampedArray()) === 'uint8clampedarray');
+assert(type(new Int16Array()) === 'int16array');
+assert(type(new Uint16Array()) === 'uint16array');
+assert(type(new Int32Array()) === 'int32array');
+assert(type(new UInt32Array()) === 'uint32array');
+assert(type(new Float32Array()) === 'float32array');
+assert(type(new Float64Array()) === 'float64array');
+assert(type(new ArrayBuffer()) === 'arraybuffer');
+assert(type(new DataView(arrayBuffer)) === 'dataview');
+```
+
+If you use `Symbol.toStringTag` to change an Objects return value of the `toString()` Method, `type()` will return this value, e.g:
+
+```js
+var myObject = {};
+myObject[Symbol.toStringTag] = 'myCustomType';
+assert(type(myObject) === 'myCustomType');
+```
+
+### Library
+
+A `Library` is a small constructed repository for custom type detections.
+
+```js
+var lib = new type.Library;
+```
+
+#### .of (obj)
+
+* **@param** _{Mixed}_ object to test
+* **@return** _{String}_ type
+
+Expose replacement `typeof` detection to the library.
+
+```js
+if (lib.of('hello world') === 'string') {
+ // ...
+}
+```
+
+
+#### .define (type, test)
+
+* **@param** _{String}_ type
+* **@param** _{RegExp|Function}_ test
+
+Add a test to for the `.test()` assertion.
+
+Can be defined as a regular expression:
+
+```js
+lib.define('int', /^[0-9]+$/);
+```
+
+... or as a function:
+
+```js
+lib.define('bln', function (obj) {
+ if (lib.of(obj) === 'boolean') return true;
+ var blns = [ 'yes', 'no', 'true', 'false', 1, 0 ];
+ if (lib.of(obj) === 'string') obj = obj.toLowerCase();
+ return !! ~blns.indexOf(obj);
+});
+```
+
+
+#### .test (obj, test)
+
+* **@param** _{Mixed}_ object
+* **@param** _{String}_ type
+* **@return** _{Boolean}_ result
+
+Assert that an object is of type. Will first
+check natives, and if that does not pass it will
+use the user defined custom tests.
+
+```js
+assert(lib.test('1', 'int'));
+assert(lib.test('yes', 'bln'));
+```

+# Release Notes
+
+## 1.0.0 / 2015-03-15
+
+Supports all new ES6 primitives, as well as Objects which override their
+toStringTag using [`Symbol.toStringTag`][1].
+
+Supports primitive Object instances over literals - for example
+`new String('foo')` and `'foo'` both report a type of `'string'`.

+section: main
+---
+
+### v2.2.2, 2014-05-01
+ - update pako to v0.2.1, fix an error when decompressing some files (see [#126](https://github.com/Stuk/jszip/issues/126)).
+
+### v2.2.1, 2014-04-23
+ - fix unreadable generated file on Windows 8 (see [#112](https://github.com/Stuk/jszip/issues/112)).
+ - replace zlibjs with pako.
+
+### v2.2.0, 2014-02-25
+ - make the `new` operator optional before the `JSZip` constructor (see [#93](https://github.com/Stuk/jszip/pull/93)).
+ - update zlibjs to v0.2.0.
+
+### v2.1.1, 2014-02-13
+ - use the npm package for zlib.js instead of the github url.
+
+### v2.1.0, 2014-02-06
+ - split the files and use Browserify to generate the final file (see [#74](https://github.com/Stuk/jszip/pull/74))
+ - packaging change : instead of 4 files (jszip.js, jszip-load.js, jszip-inflate.js, jszip-deflate.js) we now have 2 files : dist/jszip.js and dist/jszip.min.js
+ - add component/bower support
+ - rename variable: 'byte' is a reserved word (see [#76](https://github.com/Stuk/jszip/pull/76))
+ - add support for the unicode path extra field (see [#82](https://github.com/Stuk/jszip/pull/82))
+ - ensure that the generated files have a header with the licenses (see [#80](https://github.com/Stuk/jszip/pull/80))
+
+# v2.0.0, 2013-10-20
+
+ - `JSZipBase64` has been renamed to `JSZip.base64`.
+ - The `data` attribute on the object returned by `zip.file(name)` has been removed. Use `asText()`, `asBinary()`, `asUint8Array()`, `asArrayBuffer()` or `asNodeBuffer()`.
+
+ - [Fix issue with Android browser](https://github.com/Stuk/jszip/pull/60)
+
+ - The compression/decompression methods now give their input type with the `compressInputType` and `uncompressInputType` attributes.
+ - Lazily decompress data when needed and [improve performance in general](https://github.com/Stuk/jszip/pull/56)
+ - [Add support for `Buffer` in Node.js](https://github.com/Stuk/jszip/pull/57).
+ - Package for CommonJS/npm.
+
+### v1.0.1, 2013-03-04
+
+ - Fixed an issue when generating a compressed zip file with empty files or folders, see #33.

+GPL version 3
+=============
+
+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.

+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state.mode === LEN
+ strm.avail_in >= 6
+ strm.avail_out >= 258
+ start >= strm.avail_out
+ state.bits < 8
+
+ On return, state.mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm.avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm.avail_out >= 258 for each loop to avoid checking for
+ output space.

+ Process a set of code lengths to create a canonical Huffman code. The

+ increments for the same length, and zeros are appended as the length

+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.
+
+ The length counts are used for other purposes as well, i.e. finding

+V. General Format of a .ZIP file
+--------------------------------
+
+ Files stored in arbitrary order. Large .ZIP files can span multiple
+ volumes or be split into user-defined segment sizes. All values
+ are stored in little-endian byte order unless otherwise specified.
+
+ Overall .ZIP file format:
+
+ [local file header 1]
+ [file data 1]
+ [data descriptor 1]
+ .
+ .
+ .
+ [local file header n]
+ [file data n]
+ [data descriptor n]
+ [archive decryption header]
+ [archive extra data record]
+ [central directory]
+ [zip64 end of central directory record]
+ [zip64 end of central directory locator]
+ [end of central directory record]
+
+
+ A. Local file header:
+
+ local file header signature 4 bytes (0x04034b50)
+ version needed to extract 2 bytes
+ general purpose bit flag 2 bytes
+ compression method 2 bytes
+ last mod file time 2 bytes
+ last mod file date 2 bytes
+ crc-32 4 bytes
+ compressed size 4 bytes
+ uncompressed size 4 bytes
+ file name length 2 bytes
+ extra field length 2 bytes
+
+ file name (variable size)
+ extra field (variable size)
+
+ B. File data
+
+ Immediately following the local header for a file
+ is the compressed or stored data for the file.
+ The series of [local file header][file data][data
+ descriptor] repeats for each file in the .ZIP archive.
+
+ C. Data descriptor:
+
+ crc-32 4 bytes
+ compressed size 4 bytes
+ uncompressed size 4 bytes
+
+ This descriptor exists only if bit 3 of the general
+ purpose bit flag is set (see below). It is byte aligned
+ and immediately follows the last byte of compressed data.
+ This descriptor is used only when it was not possible to
+ seek in the output .ZIP file, e.g., when the output .ZIP file
+ was standard output or a non-seekable device. For ZIP64(tm) format
+ archives, the compressed and uncompressed sizes are 8 bytes each.
+
+ When compressing files, compressed and uncompressed sizes
+ should be stored in ZIP64 format (as 8 byte values) when a
+ files size exceeds 0xFFFFFFFF. However ZIP64 format may be
+ used regardless of the size of a file. When extracting, if
+ the zip64 extended information extra field is present for
+ the file the compressed and uncompressed sizes will be 8
+ byte values.
+
+ Although not originally assigned a signature, the value
+ 0x08074b50 has commonly been adopted as a signature value
+ for the data descriptor record. Implementers should be
+ aware that ZIP files may be encountered with or without this
+ signature marking data descriptors and should account for
+ either case when reading ZIP files to ensure compatibility.
+ When writing ZIP files, it is recommended to include the
+ signature value marking the data descriptor record. When
+ the signature is used, the fields currently defined for
+ the data descriptor record will immediately follow the
+ signature.
+
+ An extensible data descriptor will be released in a future
+ version of this APPNOTE. This new record is intended to
+ resolve conflicts with the use of this record going forward,
+ and to provide better support for streamed file processing.
+
+ When the Central Directory Encryption method is used, the data
+ descriptor record is not required, but may be used. If present,
+ and bit 3 of the general purpose bit field is set to indicate
+ its presence, the values in fields of the data descriptor
+ record should be set to binary zeros.
+
+ D. Archive decryption header:
+
+ The Archive Decryption Header is introduced in version 6.2
+ of the ZIP format specification. This record exists in support
+ of the Central Directory Encryption Feature implemented as part of
+ the Strong Encryption Specification as described in this document.
+ When the Central Directory Structure is encrypted, this decryption
+ header will precede the encrypted data segment. The encrypted
+ data segment will consist of the Archive extra data record (if
+ present) and the encrypted Central Directory Structure data.
+ The format of this data record is identical to the Decryption
+ header record preceding compressed file data. If the central
+ directory structure is encrypted, the location of the start of
+ this data record is determined using the Start of Central Directory
+ field in the Zip64 End of Central Directory record. Refer to the
+ section on the Strong Encryption Specification for information
+ on the fields used in the Archive Decryption Header record.
+
+
+ E. Archive extra data record:
+
+ archive extra data signature 4 bytes (0x08064b50)
+ extra field length 4 bytes
+ extra field data (variable size)
+
+ The Archive Extra Data Record is introduced in version 6.2
+ of the ZIP format specification. This record exists in support
+ of the Central Directory Encryption Feature implemented as part of
+ the Strong Encryption Specification as described in this document.
+ When present, this record immediately precedes the central
+ directory data structure. The size of this data record will be
+ included in the Size of the Central Directory field in the
+ End of Central Directory record. If the central directory structure
+ is compressed, but not encrypted, the location of the start of
+ this data record is determined using the Start of Central Directory
+ field in the Zip64 End of Central Directory record.
+
+
+ F. Central directory structure:
+
+ [file header 1]
+ .
+ .
+ .
+ [file header n]
+ [digital signature]
+
+ File header:
+
+ central file header signature 4 bytes (0x02014b50)
+ version made by 2 bytes
+ version needed to extract 2 bytes
+ general purpose bit flag 2 bytes
+ compression method 2 bytes
+ last mod file time 2 bytes
+ last mod file date 2 bytes
+ crc-32 4 bytes
+ compressed size 4 bytes
+ uncompressed size 4 bytes
+ file name length 2 bytes
+ extra field length 2 bytes
+ file comment length 2 bytes
+ disk number start 2 bytes
+ internal file attributes 2 bytes
+ external file attributes 4 bytes
+ relative offset of local header 4 bytes
+
+ file name (variable size)
+ extra field (variable size)
+ file comment (variable size)
+
+ Digital signature:
+
+ header signature 4 bytes (0x05054b50)
+ size of data 2 bytes
+ signature data (variable size)
+
+ With the introduction of the Central Directory Encryption
+ feature in version 6.2 of this specification, the Central
+ Directory Structure may be stored both compressed and encrypted.
+ Although not required, it is assumed when encrypting the
+ Central Directory Structure, that it will be compressed
+ for greater storage efficiency. Information on the
+ Central Directory Encryption feature can be found in the section
+ describing the Strong Encryption Specification. The Digital
+ Signature record will be neither compressed nor encrypted.
+
+ G. Zip64 end of central directory record
+
+ zip64 end of central dir
+ signature 4 bytes (0x06064b50)
+ size of zip64 end of central
+ directory record 8 bytes
+ version made by 2 bytes
+ version needed to extract 2 bytes
+ number of this disk 4 bytes
+ number of the disk with the
+ start of the central directory 4 bytes
+ total number of entries in the
+ central directory on this disk 8 bytes
+ total number of entries in the
+ central directory 8 bytes
+ size of the central directory 8 bytes
+ offset of start of central
+ directory with respect to
+ the starting disk number 8 bytes
+ zip64 extensible data sector (variable size)
+
+ The value stored into the "size of zip64 end of central
+ directory record" should be the size of the remaining
+ record and should not include the leading 12 bytes.
+
+ Size = SizeOfFixedFields + SizeOfVariableData - 12.
+
+ The above record structure defines Version 1 of the
+ zip64 end of central directory record. Version 1 was
+ implemented in versions of this specification preceding
+ 6.2 in support of the ZIP64 large file feature. The
+ introduction of the Central Directory Encryption feature
+ implemented in version 6.2 as part of the Strong Encryption
+ Specification defines Version 2 of this record structure.
+ Refer to the section describing the Strong Encryption
+ Specification for details on the version 2 format for
+ this record.
+
+ Special purpose data may reside in the zip64 extensible data
+ sector field following either a V1 or V2 version of this
+ record. To ensure identification of this special purpose data
+ it must include an identifying header block consisting of the
+ following:
+
+ Header ID - 2 bytes
+ Data Size - 4 bytes
+
+ The Header ID field indicates the type of data that is in the
+ data block that follows.
+
+ Data Size identifies the number of bytes that follow for this
+ data block type.
+
+ Multiple special purpose data blocks may be present, but each
+ must be preceded by a Header ID and Data Size field. Current
+ mappings of Header ID values supported in this field are as
+ defined in APPENDIX C.
+
+ H. Zip64 end of central directory locator
+
+ zip64 end of central dir locator
+ signature 4 bytes (0x07064b50)
+ number of the disk with the
+ start of the zip64 end of
+ central directory 4 bytes
+ relative offset of the zip64
+ end of central directory record 8 bytes
+ total number of disks 4 bytes
+
+ I. End of central directory record:
+
+ end of central dir signature 4 bytes (0x06054b50)
+ number of this disk 2 bytes
+ number of the disk with the
+ start of the central directory 2 bytes
+ total number of entries in the
+ central directory on this disk 2 bytes
+ total number of entries in
+ the central directory 2 bytes
+ size of the central directory 4 bytes
+ offset of start of central
+ directory with respect to
+ the starting disk number 4 bytes
+ .ZIP file comment length 2 bytes
+ .ZIP file comment (variable size)
+
+ J. Explanation of fields:
+
+ version made by (2 bytes)
+
+ The upper byte indicates the compatibility of the file
+ attribute information. If the external file attributes
+ are compatible with MS-DOS and can be read by PKZIP for
+ DOS version 2.04g then this value will be zero. If these
+ attributes are not compatible, then this value will
+ identify the host system on which the attributes are
+ compatible. Software can use this information to determine
+ the line record format for text files etc. The current
+ mappings are:
+
+ 0 - MS-DOS and OS/2 (FAT / VFAT / FAT32 file systems)
+ 1 - Amiga 2 - OpenVMS
+ 3 - UNIX 4 - VM/CMS
+ 5 - Atari ST 6 - OS/2 H.P.F.S.
+ 7 - Macintosh 8 - Z-System
+ 9 - CP/M 10 - Windows NTFS
+ 11 - MVS (OS/390 - Z/OS) 12 - VSE
+ 13 - Acorn Risc 14 - VFAT
+ 15 - alternate MVS 16 - BeOS
+ 17 - Tandem 18 - OS/400
+ 19 - OS/X (Darwin) 20 thru 255 - unused
+
+ The lower byte indicates the ZIP specification version
+ (the version of this document) supported by the software
+ used to encode the file. The value/10 indicates the major
+ version number, and the value mod 10 is the minor version
+ number.
+
+ version needed to extract (2 bytes)
+
+ The minimum supported ZIP specification version needed to
+ extract the file, mapped as above. This value is based on
+ the specific format features a ZIP program must support to
+ be able to extract the file. If multiple features are
+ applied to a file, the minimum version should be set to the
+ feature having the highest value. New features or feature
+ changes affecting the published format specification will be
+ implemented using higher version numbers than the last
+ published value to avoid conflict.
+
+ Current minimum feature versions are as defined below:
+
+ 1.0 - Default value
+ 1.1 - File is a volume label
+ 2.0 - File is a folder (directory)
+ 2.0 - File is compressed using Deflate compression
+ 2.0 - File is encrypted using traditional PKWARE encryption
+ 2.1 - File is compressed using Deflate64(tm)
+ 2.5 - File is compressed using PKWARE DCL Implode
+ 2.7 - File is a patch data set
+ 4.5 - File uses ZIP64 format extensions
+ 4.6 - File is compressed using BZIP2 compression*
+ 5.0 - File is encrypted using DES
+ 5.0 - File is encrypted using 3DES
+ 5.0 - File is encrypted using original RC2 encryption
+ 5.0 - File is encrypted using RC4 encryption
+ 5.1 - File is encrypted using AES encryption
+ 5.1 - File is encrypted using corrected RC2 encryption**
+ 5.2 - File is encrypted using corrected RC2-64 encryption**
+ 6.1 - File is encrypted using non-OAEP key wrapping***
+ 6.2 - Central directory encryption
+ 6.3 - File is compressed using LZMA
+ 6.3 - File is compressed using PPMd+
+ 6.3 - File is encrypted using Blowfish
+ 6.3 - File is encrypted using Twofish
+
+
+ * Early 7.x (pre-7.2) versions of PKZIP incorrectly set the
+ version needed to extract for BZIP2 compression to be 50
+ when it should have been 46.
+
+ ** Refer to the section on Strong Encryption Specification
+ for additional information regarding RC2 corrections.
+
+ *** Certificate encryption using non-OAEP key wrapping is the
+ intended mode of operation for all versions beginning with 6.1.
+ Support for OAEP key wrapping should only be used for
+ backward compatibility when sending ZIP files to be opened by
+ versions of PKZIP older than 6.1 (5.0 or 6.0).
+
+ + Files compressed using PPMd should set the version
+ needed to extract field to 6.3, however, not all ZIP
+ programs enforce this and may be unable to decompress
+ data files compressed using PPMd if this value is set.
+
+ When using ZIP64 extensions, the corresponding value in the
+ zip64 end of central directory record should also be set.
+ This field should be set appropriately to indicate whether
+ Version 1 or Version 2 format is in use.
+
+ general purpose bit flag: (2 bytes)
+
+ Bit 0: If set, indicates that the file is encrypted.
+
+ (For Method 6 - Imploding)
+ Bit 1: If the compression method used was type 6,
+ Imploding, then this bit, if set, indicates
+ an 8K sliding dictionary was used. If clear,
+ then a 4K sliding dictionary was used.
+ Bit 2: If the compression method used was type 6,
+ Imploding, then this bit, if set, indicates
+ 3 Shannon-Fano trees were used to encode the
+ sliding dictionary output. If clear, then 2
+ Shannon-Fano trees were used.
+
+ (For Methods 8 and 9 - Deflating)
+ Bit 2 Bit 1
+ 0 0 Normal (-en) compression option was used.
+ 0 1 Maximum (-exx/-ex) compression option was used.
+ 1 0 Fast (-ef) compression option was used.
+ 1 1 Super Fast (-es) compression option was used.
+
+ (For Method 14 - LZMA)
+ Bit 1: If the compression method used was type 14,
+ LZMA, then this bit, if set, indicates
+ an end-of-stream (EOS) marker is used to
+ mark the end of the compressed data stream.
+ If clear, then an EOS marker is not present
+ and the compressed data size must be known
+ to extract.
+
+ Note: Bits 1 and 2 are undefined if the compression
+ method is any other.
+
+ Bit 3: If this bit is set, the fields crc-32, compressed
+ size and uncompressed size are set to zero in the
+ local header. The correct values are put in the
+ data descriptor immediately following the compressed
+ data. (Note: PKZIP version 2.04g for DOS only
+ recognizes this bit for method 8 compression, newer
+ versions of PKZIP recognize this bit for any
+ compression method.)
+
+ Bit 4: Reserved for use with method 8, for enhanced
+ deflating.
+
+ Bit 5: If this bit is set, this indicates that the file is
+ compressed patched data. (Note: Requires PKZIP
+ version 2.70 or greater)
+
+ Bit 6: Strong encryption. If this bit is set, you should
+ set the version needed to extract value to at least
+ 50 and you must also set bit 0. If AES encryption
+ is used, the version needed to extract value must
+ be at least 51.
+
+ Bit 7: Currently unused.
+
+ Bit 8: Currently unused.
+
+ Bit 9: Currently unused.
+
+ Bit 10: Currently unused.
+
+ Bit 11: Language encoding flag (EFS). If this bit is set,
+ the filename and comment fields for this file
+ must be encoded using UTF-8. (see APPENDIX D)
+
+ Bit 12: Reserved by PKWARE for enhanced compression.
+
+ Bit 13: Used when encrypting the Central Directory to indicate
+ selected data values in the Local Header are masked to
+ hide their actual values. See the section describing
+ the Strong Encryption Specification for details.
+
+ Bit 14: Reserved by PKWARE.
+
+ Bit 15: Reserved by PKWARE.
+
+ compression method: (2 bytes)
+
+ (see accompanying documentation for algorithm
+ descriptions)
+
+ 0 - The file is stored (no compression)
+ 1 - The file is Shrunk
+ 2 - The file is Reduced with compression factor 1
+ 3 - The file is Reduced with compression factor 2
+ 4 - The file is Reduced with compression factor 3
+ 5 - The file is Reduced with compression factor 4
+ 6 - The file is Imploded
+ 7 - Reserved for Tokenizing compression algorithm
+ 8 - The file is Deflated
+ 9 - Enhanced Deflating using Deflate64(tm)
+ 10 - PKWARE Data Compression Library Imploding (old IBM TERSE)
+ 11 - Reserved by PKWARE
+ 12 - File is compressed using BZIP2 algorithm
+ 13 - Reserved by PKWARE
+ 14 - LZMA (EFS)
+ 15 - Reserved by PKWARE
+ 16 - Reserved by PKWARE
+ 17 - Reserved by PKWARE
+ 18 - File is compressed using IBM TERSE (new)
+ 19 - IBM LZ77 z Architecture (PFS)
+ 97 - WavPack compressed data
+ 98 - PPMd version I, Rev 1
+
+ date and time fields: (2 bytes each)
+
+ The date and time are encoded in standard MS-DOS format.
+ If input came from standard input, the date and time are
+ those at which compression was started for this data.
+ If encrypting the central directory and general purpose bit
+ flag 13 is set indicating masking, the value stored in the
+ Local Header will be zero.
+
+ CRC-32: (4 bytes)
+
+ The CRC-32 algorithm was generously contributed by
+ David Schwaderer and can be found in his excellent
+ book "C Programmers Guide to NetBIOS" published by
+ Howard W. Sams & Co. Inc. The 'magic number' for
+ the CRC is 0xdebb20e3. The proper CRC pre and post
+ conditioning is used, meaning that the CRC register
+ is pre-conditioned with all ones (a starting value
+ of 0xffffffff) and the value is post-conditioned by
+ taking the one's complement of the CRC residual.
+ If bit 3 of the general purpose flag is set, this
+ field is set to zero in the local header and the correct
+ value is put in the data descriptor and in the central
+ directory. When encrypting the central directory, if the
+ local header is not in ZIP64 format and general purpose
+ bit flag 13 is set indicating masking, the value stored
+ in the Local Header will be zero.
+
+ compressed size: (4 bytes)
+ uncompressed size: (4 bytes)
+
+ The size of the file compressed and uncompressed,
+ respectively. When a decryption header is present it will
+ be placed in front of the file data and the value of the
+ compressed file size will include the bytes of the decryption
+ header. If bit 3 of the general purpose bit flag is set,
+ these fields are set to zero in the local header and the
+ correct values are put in the data descriptor and
+ in the central directory. If an archive is in ZIP64 format
+ and the value in this field is 0xFFFFFFFF, the size will be
+ in the corresponding 8 byte ZIP64 extended information
+ extra field. When encrypting the central directory, if the
+ local header is not in ZIP64 format and general purpose bit
+ flag 13 is set indicating masking, the value stored for the
+ uncompressed size in the Local Header will be zero.
+
+ file name length: (2 bytes)
+ extra field length: (2 bytes)
+ file comment length: (2 bytes)
+
+ The length of the file name, extra field, and comment
+ fields respectively. The combined length of any
+ directory record and these three fields should not
+ generally exceed 65,535 bytes. If input came from standard
+ input, the file name length is set to zero.
+
+ disk number start: (2 bytes)
+
+ The number of the disk on which this file begins. If an
+ archive is in ZIP64 format and the value in this field is
+ 0xFFFF, the size will be in the corresponding 4 byte zip64
+ extended information extra field.
+
+ internal file attributes: (2 bytes)
+
+ Bits 1 and 2 are reserved for use by PKWARE.
+
+ The lowest bit of this field indicates, if set, that
+ the file is apparently an ASCII or text file. If not
+ set, that the file apparently contains binary data.
+ The remaining bits are unused in version 1.0.
+
+ The 0x0002 bit of this field indicates, if set, that a
+ 4 byte variable record length control field precedes each
+ logical record indicating the length of the record. The
+ record length control field is stored in little-endian byte
+ order. This flag is independent of text control characters,
+ and if used in conjunction with text data, includes any
+ control characters in the total length of the record. This
+ value is provided for mainframe data transfer support.
+
+ external file attributes: (4 bytes)
+
+ The mapping of the external attributes is
+ host-system dependent (see 'version made by'). For
+ MS-DOS, the low order byte is the MS-DOS directory
+ attribute byte. If input came from standard input, this
+ field is set to zero.
+
+ relative offset of local header: (4 bytes)
+
+ This is the offset from the start of the first disk on
+ which this file appears, to where the local header should
+ be found. If an archive is in ZIP64 format and the value
+ in this field is 0xFFFFFFFF, the size will be in the
+ corresponding 8 byte zip64 extended information extra field.
+
+ file name: (Variable)
+
+ The name of the file, with optional relative path.
+ The path stored should not contain a drive or
+ device letter, or a leading slash. All slashes
+ should be forward slashes '/' as opposed to
+ backwards slashes '\' for compatibility with Amiga
+ and UNIX file systems etc. If input came from standard
+ input, there is no file name field. If encrypting
+ the central directory and general purpose bit flag 13 is set
+ indicating masking, the file name stored in the Local Header
+ will not be the actual file name. A masking value consisting
+ of a unique hexadecimal value will be stored. This value will
+ be sequentially incremented for each file in the archive. See
+ the section on the Strong Encryption Specification for details
+ on retrieving the encrypted file name.
+
+ extra field: (Variable)
+
+ This is for expansion. If additional information
+ needs to be stored for special needs or for specific
+ platforms, it should be stored here. Earlier versions
+ of the software can then safely skip this file, and
+ find the next file or header. This field will be 0
+ length in version 1.0.
+
+ In order to allow different programs and different types
+ of information to be stored in the 'extra' field in .ZIP
+ files, the following structure should be used for all
+ programs storing data in this field:
+
+ header1+data1 + header2+data2 . . .
+
+ Each header should consist of:
+
+ Header ID - 2 bytes
+ Data Size - 2 bytes
+
+ Note: all fields stored in Intel low-byte/high-byte order.
+
+ The Header ID field indicates the type of data that is in
+ the following data block.
+
+ Header ID's of 0 thru 31 are reserved for use by PKWARE.
+ The remaining ID's can be used by third party vendors for
+ proprietary usage.
+
+ The current Header ID mappings defined by PKWARE are:
+
+ 0x0001 Zip64 extended information extra field
+ 0x0007 AV Info
+ 0x0008 Reserved for extended language encoding data (PFS)

+ Detailed descriptions of Extra Fields defined by third
+ party mappings will be documented as information on
+ these data structures is made available to PKWARE.
+ PKWARE does not guarantee the accuracy of any published
+ third party data.
+
+ The Data Size field indicates the size of the following
+ data block. Programs can use this value to skip to the
+ next header block, passing over any data blocks that are
+ not of interest.
+
+ Note: As stated above, the size of the entire .ZIP file
+ header, including the file name, comment, and extra
+ field should not exceed 64K in size.
+
+ In case two different programs should appropriate the same
+ Header ID value, it is strongly recommended that each
+ program place a unique signature of at least two bytes in
+ size (and preferably 4 bytes or bigger) at the start of
+ each data area. Every program should verify that its
+ unique signature is present, in addition to the Header ID
+ value being correct, before assuming that it is a block of
+ known type.
+
+ -Zip64 Extended Information Extra Field (0x0001):
+
+ The following is the layout of the zip64 extended
+ information "extra" block. If one of the size or
+ offset fields in the Local or Central directory
+ record is too small to hold the required data,
+ a Zip64 extended information record is created.
+ The order of the fields in the zip64 extended
+ information record is fixed, but the fields will
+ only appear if the corresponding Local or Central
+ directory record field is set to 0xFFFF or 0xFFFFFFFF.
+
+ Note: all fields stored in Intel low-byte/high-byte order.
+
+ Value Size Description
+ ----- ---- -----------
+ (ZIP64) 0x0001 2 bytes Tag for this "extra" block type
+ Size 2 bytes Size of this "extra" block
+ Original
+ Size 8 bytes Original uncompressed file size
+ Compressed
+ Size 8 bytes Size of compressed data
+ Relative Header
+ Offset 8 bytes Offset of local header record
+ Disk Start
+ Number 4 bytes Number of the disk on which
+ this file starts
+
+ This entry in the Local header must include BOTH original
+ and compressed file size fields. If encrypting the
+ central directory and bit 13 of the general purpose bit
+ flag is set indicating masking, the value stored in the
+ Local Header for the original file size will be zero.
+
+
+ -OS/2 Extra Field (0x0009):
+
+ The following is the layout of the OS/2 attributes "extra"
+ block. (Last Revision 09/05/95)

+ compressed and then stored in it's entirety within this
+ structure. There will only ever be one "block" of data in
+ VarFields[].
+
+ -NTFS Extra Field (0x000a):
+
+ The following is the layout of the NTFS attributes
+ "extra" block. (Note: At this time the Mtime, Atime
+ and Ctime values may be used on any WIN32 system.)
+
+ Note: all fields stored in Intel low-byte/high-byte order.
+
+ Value Size Description
+ ----- ---- -----------
+ (NTFS) 0x000a 2 bytes Tag for this "extra" block type
+ TSize 2 bytes Size of the total "extra" block
+ Reserved 4 bytes Reserved for future use

+ .
+ .
+ .
+ TagN 2 bytes NTFS attribute tag value #N
+ SizeN 2 bytes Size of attribute #N, in bytes
+ (var.) SizeN Attribute #N data
+
+ For NTFS, values for Tag1 through TagN are as follows:
+ (currently only one set of attributes is defined for NTFS)
+
+ Tag Size Description
+ ----- ---- -----------
+ 0x0001 2 bytes Tag for attribute #1
+ Size1 2 bytes Size of attribute #1, in bytes
+ Mtime 8 bytes File last modification time
+ Atime 8 bytes File last access time
+ Ctime 8 bytes File creation time
+
+ -OpenVMS Extra Field (0x000c):
+
+ The following is the layout of the OpenVMS attributes
+ "extra" block.
+
+ Note: all fields stored in Intel low-byte/high-byte order.
+
+ Value Size Description
+ ----- ---- -----------
+ (VMS) 0x000c 2 bytes Tag for this "extra" block type
+ TSize 2 bytes Size of the total "extra" block
+ CRC 4 bytes 32-bit CRC for remainder of the block
+ Tag1 2 bytes OpenVMS attribute tag value #1

+ SizeN 2 bytes Size of attribute #N, in bytes
+ (var.) SizeN Attribute #N data
+
+ Rules:
+
+ 1. There will be one or more of attributes present, which
+ will each be preceded by the above TagX & SizeX values.
+ These values are identical to the ATR$C_XXXX and
+ ATR$S_XXXX constants which are defined in ATR.H under
+ OpenVMS C. Neither of these values will ever be zero.
+
+ 2. No word alignment or padding is performed.
+
+ 3. A well-behaved PKZIP/OpenVMS program should never produce
+ more than one sub-block with the same TagX value. Also,
+ there will never be more than one "extra" block of type
+ 0x000c in a particular directory record.
+
+ -UNIX Extra Field (0x000d):
+
+ The following is the layout of the UNIX "extra" block.
+ Note: all fields are stored in Intel low-byte/high-byte
+ order.

+ TSize 2 bytes Size for the following data block
+ Atime 4 bytes File last access time
+ Mtime 4 bytes File last modification time
+ Uid 2 bytes File user ID
+ Gid 2 bytes File group ID
+ (var) variable Variable length data field
+
+ The variable length data field will contain file type
+ specific data. Currently the only values allowed are
+ the original "linked to" file names for hard or symbolic
+ links, and the major and minor device node numbers for
+ character and block device nodes. Since device nodes
+ cannot be either symbolic or hard links, only one set of
+ variable length data is stored. Link files will have the
+ name of the original file stored. This name is NOT NULL
+ terminated. Its size can be determined by checking TSize -
+ 12. Device entries will have eight bytes stored as two 4
+ byte entries (in little endian format). The first entry
+ will be the major device number, and the second the minor
+ device number.
+
+ -PATCH Descriptor Extra Field (0x000f):
+
+ The following is the layout of the Patch Descriptor "extra"
+ block.
+
+ Note: all fields stored in Intel low-byte/high-byte order.

+
+ This field contains information about each of the certificates
+ used in encryption processing and it can be used to identify who is
+ allowed to decrypt encrypted files. This field should only appear
+ in the archive extra data record. This field is not required and
+ serves only to aide archive modifications by preserving public

+
+ -ZipIt Macintosh Extra Field (short, for files) (0x2705):
+
+ The following is the layout of a shortened variant of the
+ ZipIt extra block for Macintosh (without "full name" entry).
+ This variant is used by ZipIt 1.3.5 and newer for entries of
+ files (not directories) that do not have a MacBinary encoded
+ file. The local-header and central-header versions are identical.
+
+ Value Size Description
+ ----- ---- -----------

+
+
+ -ZipIt Macintosh Extra Field (short, for directories) (0x2805):
+
+ The following is the layout of a shortened variant of the
+ ZipIt extra block for Macintosh used only for directory
+ entries. This variant is used by ZipIt 1.3.5 and newer to
+ save some optional Mac-specific information about directories.
+ The local-header and central-header versions are identical.
+
+ Value Size Description

+ when the archive contents are viewed in ZipIt.
+ bits 1-15 reserved, zero;
+
+
+ -FWKCS MD5 Extra Field (0x4b46):
+
+ The FWKCS Contents_Signature System, used in
+ automatically identifying files independent of file name,
+ optionally adds and uses an extra field to support the
+ rapid creation of an enhanced contents_signature:
+
+ Header ID = 0x4b46
+ Data Size = 0x0013
+ Preface = 'M','D','5'
+ followed by 16 bytes containing the uncompressed file's
+ 128_bit MD5 hash(1), low byte first.
+
+ When FWKCS revises a .ZIP file central directory to add
+ this extra field for a file, it also replaces the
+ central directory entry for that file's uncompressed
+ file length with a measured value.
+
+ FWKCS provides an option to strip this extra field, if
+ present, from a .ZIP file central directory. In adding
+ this extra field, FWKCS preserves .ZIP file Authenticity
+ Verification; if stripping this extra field, FWKCS
+ preserves all versions of AV through PKZIP version 2.04g.
+
+ FWKCS, and FWKCS Contents_Signature System, are

+
+ -Info-ZIP Unicode Comment Extra Field (0x6375):
+
+ Stores the UTF-8 version of the file comment as stored in the
+ central directory header. (Last Revision 20070912)
+
+ Value Size Description
+ ----- ---- -----------
+ (UCom) 0x6375 Short tag for this extra block type ("uc")
+ TSize Short total data size for this block
+ Version 1 byte version of this extra field, currently 1
+ ComCRC32 4 bytes Comment Field CRC32 Checksum
+ UnicodeCom Variable UTF-8 version of the entry comment
+
+ Currently Version is set to the number 1. If there is a need
+ to change this field, the version will be incremented. Changes
+ may not be backward compatible so this extra field should not be
+ used if the version is not recognized.
+
+ The ComCRC32 is the standard zip CRC32 checksum of the File Comment
+ field in the central directory header. This is used to verify that
+ the comment field has not changed since the Unicode Comment extra field
+ was created. This can happen if a utility changes the File Comment
+ field but does not update the UTF-8 Comment extra field. If the CRC
+ check fails, this Unicode Comment extra field should be ignored and
+ the File Comment field in the header should be used instead.
+
+ The UnicodeCom field is the UTF-8 version of the File Comment field
+ in the header. As UnicodeCom is defined to be UTF-8, no UTF-8 byte
+ order mark (BOM) is used. The length of this field is determined by
+ subtracting the size of the previous fields from TSize. If both the
+ File Name and Comment fields are UTF-8, the new General Purpose Bit
+ Flag, bit 11 (Language encoding flag (EFS)), can be used to indicate
+ both the header File Name and Comment fields are UTF-8 and, in this
+ case, the Unicode Path and Unicode Comment extra fields are not
+ needed and should not be created. Note that, for backward
+ compatibility, bit 11 should only be used if the native character set
+ of the paths and comments being zipped up are already in UTF-8. It is
+ expected that the same file comment storage method, either general
+ purpose bit 11 or extra fields, be used in both the Local and Central
+ Directory Header for a file.
+
+
+ -Info-ZIP Unicode Path Extra Field (0x7075):
+
+ Stores the UTF-8 version of the file name field as stored in the
+ local header and central directory header. (Last Revision 20070912)
+
+ Value Size Description
+ ----- ---- -----------
+ (UPath) 0x7075 Short tag for this extra block type ("up")
+ TSize Short total data size for this block
+ Version 1 byte version of this extra field, currently 1
+ NameCRC32 4 bytes File Name Field CRC32 Checksum
+ UnicodeName Variable UTF-8 version of the entry File Name
+
+ Currently Version is set to the number 1. If there is a need
+ to change this field, the version will be incremented. Changes
+ may not be backward compatible so this extra field should not be
+ used if the version is not recognized.
+
+ The NameCRC32 is the standard zip CRC32 checksum of the File Name
+ field in the header. This is used to verify that the header
+ File Name field has not changed since the Unicode Path extra field
+ was created. This can happen if a utility renames the File Name but
+ does not update the UTF-8 path extra field. If the CRC check fails,
+ this UTF-8 Path Extra Field should be ignored and the File Name field
+ in the header should be used instead.
+
+ The UnicodeName is the UTF-8 version of the contents of the File Name
+ field in the header. As UnicodeName is defined to be UTF-8, no UTF-8
+ byte order mark (BOM) is used. The length of this field is determined
+ by subtracting the size of the previous fields from TSize. If both
+ the File Name and Comment fields are UTF-8, the new General Purpose
+ Bit Flag, bit 11 (Language encoding flag (EFS)), can be used to
+ indicate that both the header File Name and Comment fields are UTF-8
+ and, in this case, the Unicode Path and Unicode Comment extra fields
+ are not needed and should not be created. Note that, for backward
+ compatibility, bit 11 should only be used if the native character set
+ of the paths and comments being zipped up are already in UTF-8. It is
+ expected that the same file name storage method, either general
+ purpose bit 11 or extra fields, be used in both the Local and Central
+ Directory Header for a file.

+ K. Splitting and Spanning ZIP files
+
+ Spanning is the process of segmenting a ZIP file across
+ multiple removable media. This support has typically only
+ been provided for DOS formatted floppy diskettes.
+
+ File splitting is a newer derivative of spanning.
+ Splitting follows the same segmentation process as
+ spanning, however, it does not require writing each
+ segment to a unique removable medium and instead supports
+ placing all pieces onto local or non-removable locations
+ such as file systems, local drives, folders, etc...
+
+ A key difference between spanned and split ZIP files is
+ that all pieces of a spanned ZIP file have the same name.
+ Since each piece is written to a separate volume, no name
+ collisions occur and each segment can reuse the original
+ .ZIP file name given to the archive.
+
+ Sequence ordering for DOS spanned archives uses the DOS
+ volume label to determine segment numbers. Volume labels
+ for each segment are written using the form PKBACK#xxx,
+ where xxx is the segment number written as a decimal
+ value from 001 - nnn.
+
+ Split ZIP files are typically written to the same location
+ and are subject to name collisions if the spanned name
+ format is used since each segment will reside on the same
+ drive. To avoid name collisions, split archives are named
+ as follows.
+
+ Segment 1 = filename.z01
+ Segment n-1 = filename.z(n-1)
+ Segment n = filename.zip
+
+ The .ZIP extension is used on the last segment to support
+ quickly reading the central directory. The segment number
+ n should be a decimal value.
+
+ Spanned ZIP files may be PKSFX Self-extracting ZIP files.
+ PKSFX files may also be split, however, in this case
+ the first segment must be named filename.exe. The first
+ segment of a split PKSFX archive must be large enough to
+ include the entire executable program.
+
+ Capacities for split archives are as follows.
+
+ Maximum number of segments = 4,294,967,295 - 1
+ Maximum .ZIP segment size = 4,294,967,295 bytes
+ Minimum segment size = 64K
+ Maximum PKSFX segment size = 2,147,483,647 bytes
+
+ Segment sizes may be different however by convention, all
+ segment sizes should be the same with the exception of the
+ last, which may be smaller. Local and central directory
+ header records must never be split across a segment boundary.
+ When writing a header record, if the number of bytes remaining
+ within a segment is less than the size of the header record,
+ end the current segment and write the header at the start
+ of the next segment. The central directory may span segment
+ boundaries, but no single record in the central directory
+ should be split across segments.
+
+ Spanned/Split archives created using PKZIP for Windows
+ (V2.50 or greater), PKZIP Command Line (V2.50 or greater),
+ or PKZIP Explorer will include a special spanning
+ signature as the first 4 bytes of the first segment of
+ the archive. This signature (0x08074b50) will be
+ followed immediately by the local header signature for
+ the first file in the archive.
+
+ A special spanning marker may also appear in spanned/split
+ archives if the spanning or splitting process starts but
+ only requires one segment. In this case the 0x08074b50
+ signature will be replaced with the temporary spanning
+ marker signature of 0x30304b50. Split archives can
+ only be uncompressed by other versions of PKZIP that
+ know how to create a split archive.
+
+ The signature value 0x08074b50 is also used by some
+ ZIP implementations as a marker for the Data Descriptor
+ record. Conflict in this alternate assignment can be
+ avoided by ensuring the position of the signature
+ within the ZIP file to determine the use for which it
+ is intended.
+
+ L. General notes:
+
+ 1) All fields unless otherwise noted are unsigned and stored
+ in Intel low-byte:high-byte, low-word:high-word order.
+
+ 2) String fields are not null terminated, since the
+ length is given explicitly.
+
+ 3) The entries in the central directory may not necessarily
+ be in the same order that files appear in the .ZIP file.
+
+ 4) If one of the fields in the end of central directory
+ record is too small to hold required data, the field
+ should be set to -1 (0xFFFF or 0xFFFFFFFF) and the
+ ZIP64 format record should be created.
+
+ 5) The end of central directory record and the
+ Zip64 end of central directory locator record must
+ reside on the same disk when splitting or spanning
+ an archive.
+
+VI. Explanation of compression methods
+--------------------------------------
+
+UnShrinking - Method 1
+----------------------
+
+Shrinking is a Dynamic Ziv-Lempel-Welch compression algorithm
+with partial clearing. The initial code size is 9 bits, and
+the maximum code size is 13 bits. Shrinking differs from
+conventional Dynamic Ziv-Lempel-Welch implementations in several
+respects:
+
+1) The code size is controlled by the compressor, and is not
+ automatically increased when codes larger than the current
+ code size are created (but not necessarily used). When
+ the decompressor encounters the code sequence 256
+ (decimal) followed by 1, it should increase the code size
+ read from the input stream to the next bit size. No
+ blocking of the codes is performed, so the next code at
+ the increased size should be read from the input stream
+ immediately after where the previous code at the smaller
+ bit size was read. Again, the decompressor should not
+ increase the code size used until the sequence 256,1 is
+ encountered.
+
+2) When the table becomes full, total clearing is not
+ performed. Rather, when the compressor emits the code
+ sequence 256,2 (decimal), the decompressor should clear
+ all leaf nodes from the Ziv-Lempel tree, and continue to
+ use the current code size. The nodes that are cleared
+ from the Ziv-Lempel tree are then re-used, with the lowest
+ code value re-used first, and the highest code value
+ re-used last. The compressor can emit the sequence 256,2
+ at any time.
+
+Expanding - Methods 2-5
+-----------------------
+
+The Reducing algorithm is actually a combination of two
+distinct algorithms. The first algorithm compresses repeated
+byte sequences, and the second algorithm takes the compressed
+stream from the first algorithm and applies a probabilistic
+compression method.
+
+The probabilistic compression stores an array of 'follower
+sets' S(j), for j=0 to 255, corresponding to each possible
+ASCII character. Each set contains between 0 and 32
+characters, to be denoted as S(j)[0],...,S(j)[m], where m<32.
+The sets are stored at the beginning of the data area for a
+Reduced file, in reverse order, with S(255) first, and S(0)
+last.
+
+The sets are encoded as { N(j), S(j)[0],...,S(j)[N(j)-1] },
+where N(j) is the size of set S(j). N(j) can be 0, in which
+case the follower set for S(j) is empty. Each N(j) value is
+encoded in 6 bits, followed by N(j) eight bit character values
+corresponding to S(j)[0] to S(j)[N(j)-1] respectively. If
+N(j) is 0, then no values for S(j) are stored, and the value
+for N(j-1) immediately follows.
+
+Immediately after the follower sets, is the compressed data
+stream. The compressed data stream can be interpreted for the
+probabilistic decompression as follows:
+
+let Last-Character <- 0.
+loop until done
+ if the follower set S(Last-Character) is empty then
+ read 8 bits from the input stream, and copy this
+ value to the output stream.
+ otherwise if the follower set S(Last-Character) is non-empty then
+ read 1 bit from the input stream.
+ if this bit is not zero then
+ read 8 bits from the input stream, and copy this
+ value to the output stream.
+ otherwise if this bit is zero then
+ read B(N(Last-Character)) bits from the input
+ stream, and assign this value to I.
+ Copy the value of S(Last-Character)[I] to the
+ output stream.
+
+ assign the last value placed on the output stream to
+ Last-Character.
+end loop
+
+B(N(j)) is defined as the minimal number of bits required to
+encode the value N(j)-1.
+
+The decompressed stream from above can then be expanded to
+re-create the original file as follows:
+
+let State <- 0.
+
+loop until done
+ read 8 bits from the input stream into C.
+ case State of
+ 0: if C is not equal to DLE (144 decimal) then
+ copy C to the output stream.
+ otherwise if C is equal to DLE then
+ let State <- 1.
+
+ 1: if C is non-zero then
+ let V <- C.
+ let Len <- L(V)
+ let State <- F(Len).
+ otherwise if C is zero then
+ copy the value 144 (decimal) to the output stream.
+ let State <- 0
+
+ 2: let Len <- Len + C
+ let State <- 3.
+
+ 3: move backwards D(V,C) bytes in the output stream
+ (if this position is before the start of the output
+ stream, then assume that all the data before the
+ start of the output stream is filled with zeros).
+ copy Len+3 bytes from this position to the output stream.
+ let State <- 0.
+ end case
+end loop
+
+The functions F,L, and D are dependent on the 'compression
+factor', 1 through 4, and are defined as follows:
+
+For compression factor 1:
+ L(X) equals the lower 7 bits of X.
+ F(X) equals 2 if X equals 127 otherwise F(X) equals 3.
+ D(X,Y) equals the (upper 1 bit of X) * 256 + Y + 1.
+For compression factor 2:
+ L(X) equals the lower 6 bits of X.
+ F(X) equals 2 if X equals 63 otherwise F(X) equals 3.
+ D(X,Y) equals the (upper 2 bits of X) * 256 + Y + 1.
+For compression factor 3:
+ L(X) equals the lower 5 bits of X.
+ F(X) equals 2 if X equals 31 otherwise F(X) equals 3.
+ D(X,Y) equals the (upper 3 bits of X) * 256 + Y + 1.
+For compression factor 4:
+ L(X) equals the lower 4 bits of X.
+ F(X) equals 2 if X equals 15 otherwise F(X) equals 3.
+ D(X,Y) equals the (upper 4 bits of X) * 256 + Y + 1.
+
+Imploding - Method 6
+--------------------
+
+The Imploding algorithm is actually a combination of two distinct
+algorithms. The first algorithm compresses repeated byte
+sequences using a sliding dictionary. The second algorithm is
+used to compress the encoding of the sliding dictionary output,
+using multiple Shannon-Fano trees.
+
+The Imploding algorithm can use a 4K or 8K sliding dictionary
+size. The dictionary size used can be determined by bit 1 in the
+general purpose flag word; a 0 bit indicates a 4K dictionary
+while a 1 bit indicates an 8K dictionary.
+
+The Shannon-Fano trees are stored at the start of the compressed
+file. The number of trees stored is defined by bit 2 in the
+general purpose flag word; a 0 bit indicates two trees stored, a
+1 bit indicates three trees are stored. If 3 trees are stored,
+the first Shannon-Fano tree represents the encoding of the
+Literal characters, the second tree represents the encoding of
+the Length information, the third represents the encoding of the
+Distance information. When 2 Shannon-Fano trees are stored, the
+Length tree is stored first, followed by the Distance tree.
+
+The Literal Shannon-Fano tree, if present is used to represent
+the entire ASCII character set, and contains 256 values. This
+tree is used to compress any data not compressed by the sliding
+dictionary algorithm. When this tree is present, the Minimum
+Match Length for the sliding dictionary is 3. If this tree is
+not present, the Minimum Match Length is 2.
+
+The Length Shannon-Fano tree is used to compress the Length part
+of the (length,distance) pairs from the sliding dictionary
+output. The Length tree contains 64 values, ranging from the
+Minimum Match Length, to 63 plus the Minimum Match Length.
+
+The Distance Shannon-Fano tree is used to compress the Distance
+part of the (length,distance) pairs from the sliding dictionary
+output. The Distance tree contains 64 values, ranging from 0 to
+63, representing the upper 6 bits of the distance value. The
+distance values themselves will be between 0 and the sliding
+dictionary size, either 4K or 8K.
+
+The Shannon-Fano trees themselves are stored in a compressed
+format. The first byte of the tree data represents the number of
+bytes of data representing the (compressed) Shannon-Fano tree
+minus 1. The remaining bytes represent the Shannon-Fano tree
+data encoded as:
+
+ High 4 bits: Number of values at this bit length + 1. (1 - 16)
+ Low 4 bits: Bit Length needed to represent value + 1. (1 - 16)
+
+The Shannon-Fano codes can be constructed from the bit lengths
+using the following algorithm:
+
+1) Sort the Bit Lengths in ascending order, while retaining the
+ order of the original lengths stored in the file.
+
+2) Generate the Shannon-Fano trees:
+
+ Code <- 0
+ CodeIncrement <- 0
+ LastBitLength <- 0
+ i <- number of Shannon-Fano codes - 1 (either 255 or 63)
+
+ loop while i >= 0
+ Code = Code + CodeIncrement
+ if BitLength(i) <> LastBitLength then
+ LastBitLength=BitLength(i)
+ CodeIncrement = 1 shifted left (16 - LastBitLength)
+ ShannonCode(i) = Code
+ i <- i - 1
+ end loop
+
+3) Reverse the order of all the bits in the above ShannonCode()
+ vector, so that the most significant bit becomes the least
+ significant bit. For example, the value 0x1234 (hex) would
+ become 0x2C48 (hex).
+
+4) Restore the order of Shannon-Fano codes as originally stored
+ within the file.
+
+Example:
+
+ This example will show the encoding of a Shannon-Fano tree
+ of size 8. Notice that the actual Shannon-Fano trees used
+ for Imploding are either 64 or 256 entries in size.
+
+Example: 0x02, 0x42, 0x01, 0x13
+
+ The first byte indicates 3 values in this table. Decoding the
+ bytes:
+ 0x42 = 5 codes of 3 bits long
+ 0x01 = 1 code of 2 bits long
+ 0x13 = 2 codes of 4 bits long
+
+ This would generate the original bit length array of:
+ (3, 3, 3, 3, 3, 2, 4, 4)
+
+ There are 8 codes in this table for the values 0 thru 7. Using
+ the algorithm to obtain the Shannon-Fano codes produces:
+
+ Reversed Order Original
+Val Sorted Constructed Code Value Restored Length
+--- ------ ----------------- -------- -------- ------
+0: 2 1100000000000000 11 101 3
+1: 3 1010000000000000 101 001 3
+2: 3 1000000000000000 001 110 3
+3: 3 0110000000000000 110 010 3
+4: 3 0100000000000000 010 100 3
+5: 3 0010000000000000 100 11 2
+6: 4 0001000000000000 1000 1000 4
+7: 4 0000000000000000 0000 0000 4
+
+The values in the Val, Order Restored and Original Length columns
+now represent the Shannon-Fano encoding tree that can be used for
+decoding the Shannon-Fano encoded data. How to parse the
+variable length Shannon-Fano values from the data stream is beyond
+the scope of this document. (See the references listed at the end of
+this document for more information.) However, traditional decoding
+schemes used for Huffman variable length decoding, such as the
+Greenlaw algorithm, can be successfully applied.
+
+The compressed data stream begins immediately after the
+compressed Shannon-Fano data. The compressed data stream can be
+interpreted as follows:
+
+loop until done
+ read 1 bit from input stream.
+
+ if this bit is non-zero then (encoded data is literal data)
+ if Literal Shannon-Fano tree is present
+ read and decode character using Literal Shannon-Fano tree.
+ otherwise
+ read 8 bits from input stream.
+ copy character to the output stream.
+ otherwise (encoded data is sliding dictionary match)
+ if 8K dictionary size
+ read 7 bits for offset Distance (lower 7 bits of offset).
+ otherwise
+ read 6 bits for offset Distance (lower 6 bits of offset).
+
+ using the Distance Shannon-Fano tree, read and decode the
+ upper 6 bits of the Distance value.
+
+ using the Length Shannon-Fano tree, read and decode
+ the Length value.
+
+ Length <- Length + Minimum Match Length
+
+ if Length = 63 + Minimum Match Length
+ read 8 bits from the input stream,
+ add this value to Length.
+
+ move backwards Distance+1 bytes in the output stream, and
+ copy Length characters from this position to the output
+ stream. (if this position is before the start of the output
+ stream, then assume that all the data before the start of
+ the output stream is filled with zeros).
+end loop
+
+Tokenizing - Method 7
+---------------------
+
+This method is not used by PKZIP.
+
+Deflating - Method 8
+--------------------
+
+The Deflate algorithm is similar to the Implode algorithm using
+a sliding dictionary of up to 32K with secondary compression
+from Huffman/Shannon-Fano codes.
+
+The compressed data is stored in blocks with a header describing
+the block and the Huffman codes used in the data block. The header
+format is as follows:
+
+ Bit 0: Last Block bit This bit is set to 1 if this is the last
+ compressed block in the data.
+ Bits 1-2: Block type
+ 00 (0) - Block is stored - All stored data is byte aligned.
+ Skip bits until next byte, then next word = block
+ length, followed by the ones compliment of the block
+ length word. Remaining data in block is the stored
+ data.
+
+ 01 (1) - Use fixed Huffman codes for literal and distance codes.
+ Lit Code Bits Dist Code Bits

+ 0 - 143 8 0 - 31 5
+ 144 - 255 9
+ 256 - 279 7
+ 280 - 287 8
+
+ Literal codes 286-287 and distance codes 30-31 are
+ never used but participate in the huffman construction.
+
+ 10 (2) - Dynamic Huffman codes. (See expanding Huffman codes)
+
+ 11 (3) - Reserved - Flag a "Error in compressed data" if seen.
+
+Expanding Huffman Codes
+-----------------------
+If the data block is stored with dynamic Huffman codes, the Huffman
+codes are sent in the following compressed format:
+
+ 5 Bits: # of Literal codes sent - 256 (256 - 286)
+ All other codes are never sent.
+ 5 Bits: # of Dist codes - 1 (1 - 32)
+ 4 Bits: # of Bit Length codes - 3 (3 - 19)
+
+The Huffman codes are sent as bit lengths and the codes are built as
+described in the implode algorithm. The bit lengths themselves are
+compressed with Huffman codes. There are 19 bit length codes:
+
+ 0 - 15: Represent bit lengths of 0 - 15
+ 16: Copy the previous bit length 3 - 6 times.
+ The next 2 bits indicate repeat length (0 = 3, ... ,3 = 6)
+ Example: Codes 8, 16 (+2 bits 11), 16 (+2 bits 10) will
+ expand to 12 bit lengths of 8 (1 + 6 + 5)
+ 17: Repeat a bit length of 0 for 3 - 10 times. (3 bits of length)
+ 18: Repeat a bit length of 0 for 11 - 138 times (7 bits of length)
+
+The lengths of the bit length codes are sent packed 3 bits per value
+(0 - 7) in the following order:
+
+ 16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15
+
+The Huffman codes should be built as described in the Implode algorithm
+except codes are assigned starting at the shortest bit length, i.e. the
+shortest code should be all 0's rather than all 1's. Also, codes with
+a bit length of zero do not participate in the tree construction. The
+codes are then used to decode the bit lengths for the literal and
+distance tables.
+
+The bit lengths for the literal tables are sent first with the number
+of entries sent described by the 5 bits sent earlier. There are up
+to 286 literal characters; the first 256 represent the respective 8
+bit character, code 256 represents the End-Of-Block code, the remaining
+29 codes represent copy lengths of 3 thru 258. There are up to 30
+distance codes representing distances from 1 thru 32k as described
+below.

+
+Enhanced Deflating - Method 9
+-----------------------------
+
+The Enhanced Deflating algorithm is similar to Deflate but
+uses a sliding dictionary of up to 64K. Deflate64(tm) is supported
+by the Deflate extractor.
+
+BZIP2 - Method 12
+-----------------
+
+BZIP2 is an open-source data compression algorithm developed by
+Julian Seward. Information and source code for this algorithm
+can be found on the internet.
+
+LZMA - Method 14 (EFS)
+----------------------
+
+LZMA is a block-oriented, general purpose data compression algorithm
+developed and maintained by Igor Pavlov. It is a derivative of LZ77
+that utilizes Markov chains and a range coder. Information and
+source code for this algorithm can be found on the internet. Consult
+with the author of this algorithm for information on terms or
+restrictions on use.
+
+Support for LZMA within the ZIP format is defined as follows:
+
+The Compression method field within the ZIP Local and Central
+Header records will be set to the value 14 to indicate data was
+compressed using LZMA.
+
+The Version needed to extract field within the ZIP Local and
+Central Header records will be set to 6.3 to indicate the
+minimum ZIP format version supporting this feature.
+
+File data compressed using the LZMA algorithm must be placed
+immediately following the Local Header for the file. If a
+standard ZIP encryption header is required, it will follow
+the Local Header and will precede the LZMA compressed file
+data segment. The location of LZMA compressed data segment
+within the ZIP format will be as shown:
+
+ [local header file 1]
+ [encryption header file 1]
+ [LZMA compressed data segment for file 1]
+ [data descriptor 1]
+ [local header file 2]
+
+The encryption header and data descriptor records may
+be conditionally present. The LZMA Compressed Data Segment
+will consist of an LZMA Properties Header followed by the
+LZMA Compressed Data as shown:
+
+ [LZMA properties header for file 1]
+ [LZMA compressed data for file 1]
+
+The LZMA Compressed Data will be stored as provided by the
+LZMA compression library. Compressed size, uncompressed
+size and other file characteristics about the file being
+compressed must be stored in standard ZIP storage format.
+
+The LZMA Properties Header will store specific data required to
+decompress the LZMA compressed Data. This data is set by the
+LZMA compression engine using the function WriteCoderProperties()
+as documented within the LZMA SDK.
+
+Storage fields for the property information within the LZMA
+Properties Header are as follows:
+
+ LZMA Version Information 2 bytes
+ LZMA Properties Size 2 bytes
+ LZMA Properties Data variable, defined by "LZMA Properties Size"
+
+LZMA Version Information - this field identifies which version of
+ the LZMA SDK was used to compress a file. The first byte will
+ store the major version number of the LZMA SDK and the second
+ byte will store the minor number.
+
+LZMA Properties Size - this field defines the size of the remaining
+ property data. Typically this size should be determined by the
+ version of the SDK. This size field is included as a convenience
+ and to help avoid any ambiguity should it arise in the future due
+ to changes in this compression algorithm.
+
+LZMA Property Data - this variable sized field records the required
+ values for the decompressor as defined by the LZMA SDK. The
+ data stored in this field should be obtained using the
+ WriteCoderProperties() in the version of the SDK defined by
+ the "LZMA Version Information" field.
+
+The layout of the "LZMA Properties Data" field is a function of the
+LZMA compression algorithm. It is possible that this layout may be
+changed by the author over time. The data layout in version 4.32
+of the LZMA SDK defines a 5 byte array that uses 4 bytes to store
+the dictionary size in little-endian order. This is preceded by a
+single packed byte as the first element of the array that contains
+the following fields:
+
+ PosStateBits
+ LiteralPosStateBits
+ LiteralContextBits
+
+Refer to the LZMA documentation for a more detailed explanation of
+these fields.
+
+Data compressed with method 14, LZMA, may include an end-of-stream
+(EOS) marker ending the compressed data stream. This marker is not
+required, but its use is highly recommended to facilitate processing
+and implementers should include the EOS marker whenever possible.
+When the EOS marker is used, general purpose bit 1 must be set. If
+general purpose bit 1 is not set, the EOS marker is not present.
+
+WavPack - Method 97
+-------------------
+
+Information describing the use of compression method 97 is
+provided by WinZIP International, LLC. This method relies on the
+open source WavPack audio compression utility developed by David Bryant.
+Information on WavPack is available at www.wavpack.com. Please consult
+with the author of this algorithm for information on terms and
+restrictions on use.
+
+WavPack data for a file begins immediately after the end of the
+local header data. This data is the output from WavPack compression
+routines. Within the ZIP file, the use of WavPack compression is
+indicated by setting the compression method field to a value of 97
+in both the local header and the central directory header. The Version
+needed to extract and version made by fields use the same values as are
+used for data compressed using the Deflate algorithm.
+
+An implementation note for storing digital sample data when using
+WavPack compression within ZIP files is that all of the bytes of
+the sample data should be compressed. This includes any unused
+bits up to the byte boundary. An example is a 2 byte sample that
+uses only 12 bits for the sample data with 4 unused bits. If only
+12 bits are passed as the sample size to the WavPack routines, the 4
+unused bits will be set to 0 on extraction regardless of their original
+state. To avoid this, the full 16 bits of the sample data size
+should be provided.
+
+PPMd - Method 98
+----------------
+
+PPMd is a data compression algorithm developed by Dmitry Shkarin
+which includes a carryless rangecoder developed by Dmitry Subbotin.
+This algorithm is based on predictive phrase matching on multiple
+order contexts. Information and source code for this algorithm
+can be found on the internet. Consult with the author of this
+algorithm for information on terms or restrictions on use.
+
+Support for PPMd within the ZIP format currently is provided only
+for version I, revision 1 of the algorithm. Storage requirements
+for using this algorithm are as follows:
+
+Parameters needed to control the algorithm are stored in the two
+bytes immediately preceding the compressed data. These bytes are
+used to store the following fields:
+
+Model order - sets the maximum model order, default is 8, possible
+ values are from 2 to 16 inclusive
+
+Sub-allocator size - sets the size of sub-allocator in MB, default is 50,
+ possible values are from 1MB to 256MB inclusive
+
+Model restoration method - sets the method used to restart context
+ model at memory insufficiency, values are:
+
+ 0 - restarts model from scratch - default
+ 1 - cut off model - decreases performance by as much as 2x
+ 2 - freeze context tree - not recommended
+
+An example for packing these fields into the 2 byte storage field is
+illustrated below. These values are stored in Intel low-byte/high-byte
+order.
+
+wPPMd = (Model order - 1) +
+ ((Sub-allocator size - 1) << 4) +
+ (Model restoration method << 12)
+
+
+VII. Traditional PKWARE Encryption
+----------------------------------
+
+The following information discusses the decryption steps
+required to support traditional PKWARE encryption. This
+form of encryption is considered weak by today's standards
+and its use is recommended only for situations with
+low security needs or for compatibility with older .ZIP
+applications.
+
+Decryption
+----------
+
+PKWARE is grateful to Mr. Roger Schlafly for his expert contribution
+towards the development of PKWARE's traditional encryption.
+
+PKZIP encrypts the compressed data stream. Encrypted files must
+be decrypted before they can be extracted.
+
+Each encrypted file has an extra 12 bytes stored at the start of
+the data area defining the encryption header for that file. The
+encryption header is originally set to random values, and then
+itself encrypted, using three, 32-bit keys. The key values are
+initialized using the supplied encryption password. After each byte
+is encrypted, the keys are then updated using pseudo-random number
+generation techniques in combination with the same CRC-32 algorithm
+used in PKZIP and described elsewhere in this document.
+
+The following is the basic steps required to decrypt a file:
+
+1) Initialize the three 32-bit keys with the password.
+2) Read and decrypt the 12-byte encryption header, further
+ initializing the encryption keys.
+3) Read and decrypt the compressed data stream using the
+ encryption keys.
+
+Step 1 - Initializing the encryption keys
+-----------------------------------------
+
+Key(0) <- 305419896
+Key(1) <- 591751049
+Key(2) <- 878082192
+
+loop for i <- 0 to length(password)-1
+ update_keys(password(i))
+end loop
+
+Where update_keys() is defined as:
+
+update_keys(char):
+ Key(0) <- crc32(key(0),char)
+ Key(1) <- Key(1) + (Key(0) & 000000ffH)
+ Key(1) <- Key(1) * 134775813 + 1
+ Key(2) <- crc32(key(2),key(1) >> 24)
+end update_keys
+
+Where crc32(old_crc,char) is a routine that given a CRC value and a
+character, returns an updated CRC value after applying the CRC-32
+algorithm described elsewhere in this document.
+
+Step 2 - Decrypting the encryption header
+-----------------------------------------
+
+The purpose of this step is to further initialize the encryption
+keys, based on random data, to render a plaintext attack on the
+data ineffective.
+
+Read the 12-byte encryption header into Buffer, in locations
+Buffer(0) thru Buffer(11).
+
+loop for i <- 0 to 11
+ C <- buffer(i) ^ decrypt_byte()
+ update_keys(C)
+ buffer(i) <- C
+end loop
+
+Where decrypt_byte() is defined as:
+
+unsigned char decrypt_byte()
+ local unsigned short temp
+ temp <- Key(2) | 2
+ decrypt_byte <- (temp * (temp ^ 1)) >> 8
+end decrypt_byte
+
+After the header is decrypted, the last 1 or 2 bytes in Buffer
+should be the high-order word/byte of the CRC for the file being
+decrypted, stored in Intel low-byte/high-byte order. Versions of
+PKZIP prior to 2.0 used a 2 byte CRC check; a 1 byte CRC check is
+used on versions after 2.0. This can be used to test if the password
+supplied is correct or not.
+
+Step 3 - Decrypting the compressed data stream
+----------------------------------------------
+
+The compressed data stream can be decrypted as follows:
+
+loop until done
+ read a character into C
+ Temp <- C ^ decrypt_byte()
+ update_keys(temp)
+ output Temp
+end loop
+
+
+VIII. Strong Encryption Specification
+-------------------------------------
+
+The Strong Encryption technology defined in this specification is
+covered under a pending patent application. The use or implementation
+in a product of certain technological aspects set forth in the current
+APPNOTE, including those with regard to strong encryption, patching,
+or extended tape operations requires a license from PKWARE. Portions
+of this Strong Encryption technology are available for use at no charge.
+Contact PKWARE for licensing terms and conditions. Refer to section II
+of this APPNOTE (Contacting PKWARE) for information on how to
+contact PKWARE.
+
+Version 5.x of this specification introduced support for strong
+encryption algorithms. These algorithms can be used with either
+a password or an X.509v3 digital certificate to encrypt each file.
+This format specification supports either password or certificate
+based encryption to meet the security needs of today, to enable
+interoperability between users within both PKI and non-PKI
+environments, and to ensure interoperability between different
+computing platforms that are running a ZIP program.
+
+Password based encryption is the most common form of encryption
+people are familiar with. However, inherent weaknesses with
+passwords (e.g. susceptibility to dictionary/brute force attack)
+as well as password management and support issues make certificate
+based encryption a more secure and scalable option. Industry
+efforts and support are defining and moving towards more advanced
+security solutions built around X.509v3 digital certificates and
+Public Key Infrastructures(PKI) because of the greater scalability,
+administrative options, and more robust security over traditional
+password based encryption.
+
+Most standard encryption algorithms are supported with this
+specification. Reference implementations for many of these
+algorithms are available from either commercial or open source
+distributors. Readily available cryptographic toolkits make
+implementation of the encryption features straight-forward.
+This document is not intended to provide a treatise on data
+encryption principles or theory. Its purpose is to document the
+data structures required for implementing interoperable data
+encryption within the .ZIP format. It is strongly recommended that
+you have a good understanding of data encryption before reading
+further.
+
+The algorithms introduced in Version 5.0 of this specification
+include:
+
+ RC2 40 bit, 64 bit, and 128 bit
+ RC4 40 bit, 64 bit, and 128 bit
+ DES
+ 3DES 112 bit and 168 bit
+
+Version 5.1 adds support for the following:
+
+ AES 128 bit, 192 bit, and 256 bit
+
+
+Version 6.1 introduces encryption data changes to support
+interoperability with Smartcard and USB Token certificate storage
+methods which do not support the OAEP strengthening standard.
+
+Version 6.2 introduces support for encrypting metadata by compressing
+and encrypting the central directory data structure to reduce information
+leakage. Information leakage can occur in legacy ZIP applications
+through exposure of information about a file even though that file is
+stored encrypted. The information exposed consists of file
+characteristics stored within the records and fields defined by this
+specification. This includes data such as a files name, its original
+size, timestamp and CRC32 value.
+
+Version 6.3 introduces support for encrypting data using the Blowfish
+and Twofish algorithms. These are symmetric block ciphers developed
+by Bruce Schneier. Blowfish supports using a variable length key from
+32 to 448 bits. Block size is 64 bits. Implementations should use 16
+rounds and the only mode supported within ZIP files is CBC. Twofish
+supports key sizes 128, 192 and 256 bits. Block size is 128 bits.
+Implementations should use 16 rounds and the only mode supported within
+ZIP files is CBC. Information and source code for both Blowfish and
+Twofish algorithms can be found on the internet. Consult with the author
+of these algorithms for information on terms or restrictions on use.
+
+Central Directory Encryption provides greater protection against
+information leakage by encrypting the Central Directory structure and
+by masking key values that are replicated in the unencrypted Local
+Header. ZIP compatible programs that cannot interpret an encrypted
+Central Directory structure cannot rely on the data in the corresponding
+Local Header for decompression information.
+
+Extra Field records that may contain information about a file that should
+not be exposed should not be stored in the Local Header and should only
+be written to the Central Directory where they can be encrypted. This
+design currently does not support streaming. Information in the End of
+Central Directory record, the Zip64 End of Central Directory Locator,
+and the Zip64 End of Central Directory records are not encrypted. Access
+to view data on files within a ZIP file with an encrypted Central Directory
+requires the appropriate password or private key for decryption prior to
+viewing any files, or any information about the files, in the archive.
+
+Older ZIP compatible programs not familiar with the Central Directory
+Encryption feature will no longer be able to recognize the Central
+Directory and may assume the ZIP file is corrupt. Programs that
+attempt streaming access using Local Headers will see invalid
+information for each file. Central Directory Encryption need not be
+used for every ZIP file. Its use is recommended for greater security.
+ZIP files not using Central Directory Encryption should operate as
+in the past.
+
+This strong encryption feature specification is intended to provide for
+scalable, cross-platform encryption needs ranging from simple password
+encryption to authenticated public/private key encryption.
+
+Encryption provides data confidentiality and privacy. It is
+recommended that you combine X.509 digital signing with encryption
+to add authentication and non-repudiation.
+
+
+Single Password Symmetric Encryption Method:
+-------------------------------------------
+
+The Single Password Symmetric Encryption Method using strong
+encryption algorithms operates similarly to the traditional
+PKWARE encryption defined in this format. Additional data
+structures are added to support the processing needs of the
+strong algorithms.
+
+The Strong Encryption data structures are:
+
+1. General Purpose Bits - Bits 0 and 6 of the General Purpose bit
+flag in both local and central header records. Both bits set
+indicates strong encryption. Bit 13, when set indicates the Central
+Directory is encrypted and that selected fields in the Local Header
+are masked to hide their actual value.
+
+
+2. Extra Field 0x0017 in central header only.
+
+ Fields to consider in this record are:
+
+ Format - the data format identifier for this record. The only
+ value allowed at this time is the integer value 2.
+
+ AlgId - integer identifier of the encryption algorithm from the
+ following range
+
+ 0x6601 - DES
+ 0x6602 - RC2 (version needed to extract < 5.2)
+ 0x6603 - 3DES 168
+ 0x6609 - 3DES 112
+ 0x660E - AES 128
+ 0x660F - AES 192
+ 0x6610 - AES 256
+ 0x6702 - RC2 (version needed to extract >= 5.2)
+ 0x6720 - Blowfish
+ 0x6721 - Twofish
+ 0x6801 - RC4
+ 0xFFFF - Unknown algorithm
+
+ Bitlen - Explicit bit length of key
+
+ 32 - 448 bits
+
+ Flags - Processing flags needed for decryption
+
+ 0x0001 - Password is required to decrypt
+ 0x0002 - Certificates only
+ 0x0003 - Password or certificate required to decrypt
+
+ Values > 0x0003 reserved for certificate processing
+
+
+3. Decryption header record preceding compressed file data.
+
+ -Decryption Header:
+
+ Value Size Description
+ ----- ---- -----------
+ IVSize 2 bytes Size of initialization vector (IV)
+ IVData IVSize Initialization vector for this file
+ Size 4 bytes Size of remaining decryption header data
+ Format 2 bytes Format definition for this record
+ AlgID 2 bytes Encryption algorithm identifier
+ Bitlen 2 bytes Bit length of encryption key
+ Flags 2 bytes Processing flags
+ ErdSize 2 bytes Size of Encrypted Random Data
+ ErdData ErdSize Encrypted Random Data
+ Reserved1 4 bytes Reserved certificate processing data
+ Reserved2 (var) Reserved for certificate processing data
+ VSize 2 bytes Size of password validation data
+ VData VSize-4 Password validation data
+ VCRC32 4 bytes Standard ZIP CRC32 of password validation data
+
+ IVData - The size of the IV should match the algorithm block size.
+ The IVData can be completely random data. If the size of
+ the randomly generated data does not match the block size
+ it should be complemented with zero's or truncated as
+ necessary. If IVSize is 0,then IV = CRC32 + Uncompressed
+ File Size (as a 64 bit little-endian, unsigned integer value).
+
+ Format - the data format identifier for this record. The only
+ value allowed at this time is the integer value 3.
+
+ AlgId - integer identifier of the encryption algorithm from the
+ following range
+
+ 0x6601 - DES
+ 0x6602 - RC2 (version needed to extract < 5.2)
+ 0x6603 - 3DES 168
+ 0x6609 - 3DES 112
+ 0x660E - AES 128
+ 0x660F - AES 192
+ 0x6610 - AES 256
+ 0x6702 - RC2 (version needed to extract >= 5.2)
+ 0x6720 - Blowfish
+ 0x6721 - Twofish
+ 0x6801 - RC4
+ 0xFFFF - Unknown algorithm
+
+ Bitlen - Explicit bit length of key
+
+ 32 - 448 bits
+
+ Flags - Processing flags needed for decryption
+
+ 0x0001 - Password is required to decrypt
+ 0x0002 - Certificates only
+ 0x0003 - Password or certificate required to decrypt
+
+ Values > 0x0003 reserved for certificate processing
+
+ ErdData - Encrypted random data is used to store random data that
+ is used to generate a file session key for encrypting
+ each file. SHA1 is used to calculate hash data used to
+ derive keys. File session keys are derived from a master
+ session key generated from the user-supplied password.
+ If the Flags field in the decryption header contains
+ the value 0x4000, then the ErdData field must be
+ decrypted using 3DES. If the value 0x4000 is not set,
+ then the ErdData field must be decrypted using AlgId.
+
+
+ Reserved1 - Reserved for certificate processing, if value is
+ zero, then Reserved2 data is absent. See the explanation
+ under the Certificate Processing Method for details on
+ this data structure.
+
+ Reserved2 - If present, the size of the Reserved2 data structure
+ is located by skipping the first 4 bytes of this field
+ and using the next 2 bytes as the remaining size. See
+ the explanation under the Certificate Processing Method
+ for details on this data structure.
+
+ VSize - This size value will always include the 4 bytes of the
+ VCRC32 data and will be greater than 4 bytes.
+
+ VData - Random data for password validation. This data is VSize
+ in length and VSize must be a multiple of the encryption
+ block size. VCRC32 is a checksum value of VData.
+ VData and VCRC32 are stored encrypted and start the
+ stream of encrypted data for a file.
+
+
+4. Useful Tips
+
+Strong Encryption is always applied to a file after compression. The
+block oriented algorithms all operate in Cypher Block Chaining (CBC)
+mode. The block size used for AES encryption is 16. All other block
+algorithms use a block size of 8. Two ID's are defined for RC2 to
+account for a discrepancy found in the implementation of the RC2
+algorithm in the cryptographic library on Windows XP SP1 and all
+earlier versions of Windows. It is recommended that zero length files
+not be encrypted, however programs should be prepared to extract them
+if they are found within a ZIP file.
+
+A pseudo-code representation of the encryption process is as follows:
+
+Password = GetUserPassword()
+MasterSessionKey = DeriveKey(SHA1(Password))
+RD = CryptographicStrengthRandomData()
+For Each File
+ IV = CryptographicStrengthRandomData()
+ VData = CryptographicStrengthRandomData()
+ VCRC32 = CRC32(VData)
+ FileSessionKey = DeriveKey(SHA1(IV + RD)
+ ErdData = Encrypt(RD,MasterSessionKey,IV)
+ Encrypt(VData + VCRC32 + FileData, FileSessionKey,IV)
+Done
+
+The function names and parameter requirements will depend on
+the choice of the cryptographic toolkit selected. Almost any
+toolkit supporting the reference implementations for each
+algorithm can be used. The RSA BSAFE(r), OpenSSL, and Microsoft
+CryptoAPI libraries are all known to work well.
+
+
+Single Password - Central Directory Encryption:
+-----------------------------------------------
+
+Central Directory Encryption is achieved within the .ZIP format by
+encrypting the Central Directory structure. This encapsulates the metadata
+most often used for processing .ZIP files. Additional metadata is stored for
+redundancy in the Local Header for each file. The process of concealing
+metadata by encrypting the Central Directory does not protect the data within
+the Local Header. To avoid information leakage from the exposed metadata
+in the Local Header, the fields containing information about a file are masked.
+
+Local Header:
+
+Masking replaces the true content of the fields for a file in the Local
+Header with false information. When masked, the Local Header is not
+suitable for streaming access and the options for data recovery of damaged
+archives is reduced. Extra Data fields that may contain confidential
+data should not be stored within the Local Header. The value set into
+the Version needed to extract field should be the correct value needed to
+extract the file without regard to Central Directory Encryption. The fields
+within the Local Header targeted for masking when the Central Directory is
+encrypted are:
+
+ Field Name Mask Value
+ ------------------ ---------------------------
+ compression method 0
+ last mod file time 0
+ last mod file date 0
+ crc-32 0
+ compressed size 0
+ uncompressed size 0
+ file name (variable size) Base 16 value from the
+ range 1 - 0xFFFFFFFFFFFFFFFF
+ represented as a string whose
+ size will be set into the
+ file name length field
+
+The Base 16 value assigned as a masked file name is simply a sequentially
+incremented value for each file starting with 1 for the first file.
+Modifications to a ZIP file may cause different values to be stored for
+each file. For compatibility, the file name field in the Local Header
+should never be left blank. As of Version 6.2 of this specification,
+the Compression Method and Compressed Size fields are not yet masked.
+Fields having a value of 0xFFFF or 0xFFFFFFFF for the ZIP64 format
+should not be masked.
+
+Encrypting the Central Directory:
+
+Encryption of the Central Directory does not include encryption of the
+Central Directory Signature data, the Zip64 End of Central Directory
+record, the Zip64 End of Central Directory Locator, or the End
+of Central Directory record. The ZIP file comment data is never
+encrypted.
+
+Before encrypting the Central Directory, it may optionally be compressed.
+Compression is not required, but for storage efficiency it is assumed
+this structure will be compressed before encrypting. Similarly, this
+specification supports compressing the Central Directory without
+requiring that it also be encrypted. Early implementations of this
+feature will assume the encryption method applied to files matches the
+encryption applied to the Central Directory.
+
+Encryption of the Central Directory is done in a manner similar to
+that of file encryption. The encrypted data is preceded by a
+decryption header. The decryption header is known as the Archive
+Decryption Header. The fields of this record are identical to
+the decryption header preceding each encrypted file. The location
+of the Archive Decryption Header is determined by the value in the
+Start of the Central Directory field in the Zip64 End of Central
+Directory record. When the Central Directory is encrypted, the
+Zip64 End of Central Directory record will always be present.
+
+The layout of the Zip64 End of Central Directory record for all
+versions starting with 6.2 of this specification will follow the
+Version 2 format. The Version 2 format is as follows:
+
+The leading fixed size fields within the Version 1 format for this
+record remain unchanged. The record signature for both Version 1
+and Version 2 will be 0x06064b50. Immediately following the last
+byte of the field known as the Offset of Start of Central
+Directory With Respect to the Starting Disk Number will begin the
+new fields defining Version 2 of this record.
+
+New fields for Version 2:
+
+Note: all fields stored in Intel low-byte/high-byte order.
+
+ Value Size Description
+ ----- ---- -----------
+ Compression Method 2 bytes Method used to compress the
+ Central Directory
+ Compressed Size 8 bytes Size of the compressed data

+ AlgId 2 bytes Encryption algorithm ID
+ BitLen 2 bytes Encryption key length
+ Flags 2 bytes Encryption flags
+ HashID 2 bytes Hash algorithm identifier
+ Hash Length 2 bytes Length of hash data
+ Hash Data (variable) Hash data
+
+The Compression Method accepts the same range of values as the
+corresponding field in the Central Header.
+
+The Compressed Size and Original Size values will not include the
+data of the Central Directory Signature which is compressed or
+encrypted.
+
+The AlgId, BitLen, and Flags fields accept the same range of values
+the corresponding fields within the 0x0017 record.
+
+Hash ID identifies the algorithm used to hash the Central Directory
+data. This data does not have to be hashed, in which case the
+values for both the HashID and Hash Length will be 0. Possible
+values for HashID are:

+ 0x0000 none
+ 0x0001 CRC32
+ 0x8003 MD5
+ 0x8004 SHA1

+
+When the Central Directory data is signed, the same hash algorithm
+used to hash the Central Directory for signing should be used.
+This is recommended for processing efficiency, however, it is
+permissible for any of the above algorithms to be used independent
+of the signing process.
+
+The Hash Data will contain the hash data for the Central Directory.
+The length of this data will vary depending on the algorithm used.
+
+The Version Needed to Extract should be set to 62.
+
+The value for the Total Number of Entries on the Current Disk will
+be 0. These records will no longer support random access when
+encrypting the Central Directory.
+
+When the Central Directory is compressed and/or encrypted, the
+End of Central Directory record will store the value 0xFFFFFFFF
+as the value for the Total Number of Entries in the Central
+Directory. The value stored in the Total Number of Entries in
+the Central Directory on this Disk field will be 0. The actual
+values will be stored in the equivalent fields of the Zip64
+End of Central Directory record.
+
+Decrypting and decompressing the Central Directory is accomplished
+in the same manner as decrypting and decompressing a file.
+
+Certificate Processing Method:
+-----------------------------
+
+The Certificate Processing Method of for ZIP file encryption
+defines the following additional data fields:
+
+1. Certificate Flag Values
+
+Additional processing flags that can be present in the Flags field of both
+the 0x0017 field of the central directory Extra Field and the Decryption
+header record preceding compressed file data are:
+
+ 0x0007 - reserved for future use
+ 0x000F - reserved for future use
+ 0x0100 - Indicates non-OAEP key wrapping was used. If this
+ this field is set, the version needed to extract must
+ be at least 61. This means OAEP key wrapping is not
+ used when generating a Master Session Key using
+ ErdData.
+ 0x4000 - ErdData must be decrypted using 3DES-168, otherwise use the
+ same algorithm used for encrypting the file contents.
+ 0x8000 - reserved for future use
+
+
+2. CertData - Extra Field 0x0017 record certificate data structure
+
+The data structure used to store certificate data within the section
+of the Extra Field defined by the CertData field of the 0x0017
+record are as shown:
+
+ Value Size Description
+ ----- ---- -----------
+ RCount 4 bytes Number of recipients.
+ HashAlg 2 bytes Hash algorithm identifier
+ HSize 2 bytes Hash size
+ SRList (var) Simple list of recipients hashed public keys
+
+
+ RCount This defines the number intended recipients whose
+ public keys were used for encryption. This identifies
+ the number of elements in the SRList.
+
+ HashAlg This defines the hash algorithm used to calculate
+ the public key hash of each public key used
+ for encryption. This field currently supports
+ only the following value for SHA-1
+
+ 0x8004 - SHA1
+
+ HSize This defines the size of a hashed public key.
+
+ SRList This is a variable length list of the hashed
+ public keys for each intended recipient. Each
+ element in this list is HSize. The total size of
+ SRList is determined using RCount * HSize.
+
+
+3. Reserved1 - Certificate Decryption Header Reserved1 Data:
+
+ Value Size Description
+ ----- ---- -----------
+ RCount 4 bytes Number of recipients.
+
+ RCount This defines the number intended recipients whose
+ public keys were used for encryption. This defines
+ the number of elements in the REList field defined below.
+
+
+4. Reserved2 - Certificate Decryption Header Reserved2 Data Structures:
+
+
+ Value Size Description
+ ----- ---- -----------
+ HashAlg 2 bytes Hash algorithm identifier
+ HSize 2 bytes Hash size
+ REList (var) List of recipient data elements
+
+
+ HashAlg This defines the hash algorithm used to calculate
+ the public key hash of each public key used
+ for encryption. This field currently supports
+ only the following value for SHA-1
+
+ 0x8004 - SHA1
+
+ HSize This defines the size of a hashed public key
+ defined in REHData.
+
+ REList This is a variable length of list of recipient data.
+ Each element in this list consists of a Recipient
+ Element data structure as follows:
+
+
+ Recipient Element (REList) Data Structure:
+
+ Value Size Description
+ ----- ---- -----------
+ RESize 2 bytes Size of REHData + REKData
+ REHData HSize Hash of recipients public key
+ REKData (var) Simple key blob
+
+
+ RESize This defines the size of an individual REList
+ element. This value is the combined size of the
+ REHData field + REKData field. REHData is defined by
+ HSize. REKData is variable and can be calculated
+ for each REList element using RESize and HSize.
+
+ REHData Hashed public key for this recipient.
+
+ REKData Simple Key Blob. The format of this data structure
+ is identical to that defined in the Microsoft
+ CryptoAPI and generated using the CryptExportKey()
+ function. The version of the Simple Key Blob
+ supported at this time is 0x02 as defined by
+ Microsoft.
+
+Certificate Processing - Central Directory Encryption:
+------------------------------------------------------
+
+Central Directory Encryption using Digital Certificates will
+operate in a manner similar to that of Single Password Central
+Directory Encryption. This record will only be present when there
+is data to place into it. Currently, data is placed into this
+record when digital certificates are used for either encrypting
+or signing the files within a ZIP file. When only password
+encryption is used with no certificate encryption or digital
+signing, this record is not currently needed. When present, this
+record will appear before the start of the actual Central Directory
+data structure and will be located immediately after the Archive
+Decryption Header if the Central Directory is encrypted.
+
+The Archive Extra Data record will be used to store the following
+information. Additional data may be added in future versions.
+
+Extra Data Fields:
+
+0x0014 - PKCS#7 Store for X.509 Certificates
+0x0016 - X.509 Certificate ID and Signature for central directory
+0x0019 - PKCS#7 Encryption Recipient Certificate List
+
+The 0x0014 and 0x0016 Extra Data records that otherwise would be
+located in the first record of the Central Directory for digital
+certificate processing. When encrypting or compressing the Central
+Directory, the 0x0014 and 0x0016 records must be located in the
+Archive Extra Data record and they should not remain in the first
+Central Directory record. The Archive Extra Data record will also
+be used to store the 0x0019 data.
+
+When present, the size of the Archive Extra Data record will be
+included in the size of the Central Directory. The data of the
+Archive Extra Data record will also be compressed and encrypted
+along with the Central Directory data structure.
+
+Certificate Processing Differences:
+
+The Certificate Processing Method of encryption differs from the
+Single Password Symmetric Encryption Method as follows. Instead
+of using a user-defined password to generate a master session key,
+cryptographically random data is used. The key material is then
+wrapped using standard key-wrapping techniques. This key material
+is wrapped using the public key of each recipient that will need
+to decrypt the file using their corresponding private key.
+
+This specification currently assumes digital certificates will follow
+the X.509 V3 format for 1024 bit and higher RSA format digital
+certificates. Implementation of this Certificate Processing Method
+requires supporting logic for key access and management. This logic
+is outside the scope of this specification.
+
+OAEP Processing with Certificate-based Encryption:
+
+OAEP stands for Optimal Asymmetric Encryption Padding. It is a
+strengthening technique used for small encoded items such as decryption
+keys. This is commonly applied in cryptographic key-wrapping techniques
+and is supported by PKCS #1. Versions 5.0 and 6.0 of this specification
+were designed to support OAEP key-wrapping for certificate-based
+decryption keys for additional security.
+
+Support for private keys stored on Smartcards or Tokens introduced
+a conflict with this OAEP logic. Most card and token products do
+not support the additional strengthening applied to OAEP key-wrapped
+data. In order to resolve this conflict, versions 6.1 and above of this
+specification will no longer support OAEP when encrypting using
+digital certificates.
+
+Versions of PKZIP available during initial development of the
+certificate processing method set a value of 61 into the
+version needed to extract field for a file. This indicates that
+non-OAEP key wrapping is used. This affects certificate encryption
+only, and password encryption functions should not be affected by
+this value. This means values of 61 may be found on files encrypted
+with certificates only, or on files encrypted with both password
+encryption and certificate encryption. Files encrypted with both
+methods can safely be decrypted using the password methods documented.
+
+IX. Change Process
+------------------
+
+In order for the .ZIP file format to remain a viable definition, this
+specification should be considered as open for periodic review and
+revision. Although this format was originally designed with a
+certain level of extensibility, not all changes in technology
+(present or future) were or will be necessarily considered in its
+design. If your application requires new definitions to the
+extensible sections in this format, or if you would like to
+submit new data structures, please forward your request to
+zipformat@pkware.com. All submissions will be reviewed by the
+ZIP File Specification Committee for possible inclusion into
+future versions of this specification. Periodic revisions
+to this specification will be published to ensure interoperability.
+We encourage comments and feedback that may help improve clarity
+or content.
+
+X. Incorporating PKWARE Proprietary Technology into Your Product
+----------------------------------------------------------------
+
+PKWARE is committed to the interoperability and advancement of the
+.ZIP format. PKWARE offers a free license for certain technological
+aspects described above under certain restrictions and conditions.
+However, the use or implementation in a product of certain technological
+aspects set forth in the current APPNOTE, including those with regard to
+strong encryption, patching, or extended tape operations requires a
+license from PKWARE. Please contact PKWARE with regard to acquiring
+a license.

+
+APPENDIX D - Language Encoding (EFS)
+------------------------------------
+
+The ZIP format has historically supported only the original IBM PC character
+encoding set, commonly referred to as IBM Code Page 437. This limits storing
+file name characters to only those within the original MS-DOS range of values
+and does not properly support file names in other character encodings, or
+languages. To address this limitation, this specification will support the
+following change.
+
+If general purpose bit 11 is unset, the file name and comment should conform
+to the original ZIP character encoding. If general purpose bit 11 is set, the
+filename and comment must support The Unicode Standard, Version 4.1.0 or
+greater using the character encoding form defined by the UTF-8 storage
+specification. The Unicode Standard is published by the The Unicode
+Consortium (www.unicode.org). UTF-8 encoded data stored within ZIP files
+is expected to not include a byte order mark (BOM).
+
+Applications may choose to supplement this file name storage through the use
+of the 0x0008 Extra Field. Storage for this optional field is currently
+undefined, however it will be used to allow storing extended information
+on source or target encoding that may further assist applications with file
+name, or file content encoding tasks. Please contact PKWARE with any
+requirements on how this field should be used.
+
+The 0x0008 Extra Field storage may be used with either setting for general
+purpose bit 11. Examples of the intended usage for this field is to store
+whether "modified-UTF-8" (JAVA) is used, or UTF-8-MAC. Similarly, other
+commonly used character encoding (code page) designations can be indicated
+through this field. Formalized values for use of the 0x0008 record remain
+undefined at this time. The definition for the layout of the 0x0008 field
+will be published when available. Use of the 0x0008 Extra Field provides
+for storing data within a ZIP file in an encoding other than IBM Code
+Page 437 or UTF-8.
+
+General purpose bit 11 will not imply any encoding of file content or
+password. Values defining character encoding for file content or
+password must be stored within the 0x0008 Extended Language Encoding
+Extra Field.
+
+Ed Gordon of the Info-ZIP group has defined a pair of "extra field" records
+that can be used to store UTF-8 file name and file comment fields. These
+records can be used for cases when the general purpose bit 11 method
+for storing UTF-8 data in the standard file name and comment fields is
+not desirable. A common case for this alternate method is if backward
+compatibility with older programs is required.
+
+Definitions for the record structure of these fields are included above
+in the section on 3rd party mappings for "extra field" records. These
+records are identified by Header ID's 0x6375 (Info-ZIP Unicode Comment
+Extra Field) and 0x7075 (Info-ZIP Unicode Path Extra Field).
+
+The choice of which storage method to use when writing a ZIP file is left
+to the implementation. Developers should expect that a ZIP file may
+contain either method and should provide support for reading data in
+either format. Use of general purpose bit 11 reduces storage requirements
+for file name data by not requiring additional "extra field" data for
+each file, but can result in older ZIP programs not being able to extract
+files. Use of the 0x6375 and 0x7075 records will result in a ZIP file
+that should always be readable by older ZIP programs, but requires more
+storage per file to write file name and/or file comment fields.
