+# base64-mc-encode
+Encoding any string (char array) to base64 in Minecraft 1.20
+
+---
+A datapack library for Minecraft 1.20 that converts string (char array) into a base64 encoded string (char array) that can be compacted with a seperate library.
+This library does not decode the base64 code as that has been implemented before for player skull decoders (i.e. [String-Parser](https://github.com/5uso/String-Parser)).
+
+## How to Use
+Once installed, you can set the string to be encoded into the `b64:convert` storage under the NBT string array tag `input`.
+Example:
+```
+data modify storage b64:convert input set value ["h","e","l","l","o"," ","w","o","r","l","d"]
+```
+To start encoding, the function is executed.
+```
+function b64:encode
+```
+
+The output will be found in `b64:convert` under the NBT string array tag `result`. You can concatenate the array using a library like [ostrmc](https://github.com/oligomc/ostrmc/).
+
+### Example
+```
+data modify storage b64:convert input set value ["N","o","t","h","i","n","g"," ","t","o"," ","s","e","e"," ","h","e","r","e"," ","4","2"]
+function b64:encode
+data get storage b64:convert result
+```
+
+Output
+```
+Storage b64:convert has the following contents: ["T", "m", "9", "0", "a", "G", "l", "u", "Z", "y", "B", "0", "b", "y", "B", "z", "Z", "W", "U", "g", "a", "G", "V", "y", "Z", "S", "A", "0", "M", "g", "=", "="]
+```
+### Allowed Characters
+Below are the characters that this datapack can read from the input string becore encoding.
+```
+ !#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\"\\]^_`abcdefghijklmnopqrstuvwxyz{|}~
+```
+
+## Building
+Building this datapack uses [beet](https://github.com/mcbeet/beet), [bolt](https://github.com/mcbeet/bolt), [mecha](https://github.com/mcbeet/mecha) and [bolt-expressions](https://github.com/rx-modules/bolt-expressions). You can install them with the commands below.
+```
+$ pip install beet bolt mecha bolt-expressions
+```
+and you can build using 
+```
+beet build
+```
+the built datapack will be found in the `build` folder.
