Qt SQL driver plugin for SQLCipher

This is a QSqlDriverPlugin for SQLCipher. It is quite simple - it uses Qt's own SQLite driver code but links against SQLCipher instead of SQLite.

Dependencies

• Qt 6 (with private header files) (for Qt5 support, look in the old qt5 branch!)
• SQLCipher
• CMake >= 3.10
• pkg-config

On a Debian-like platform, you need to install the Qt6 private-dev packages:

	apt install qt6-base-dev qt6-base-private-dev libsodium-dev

Tested platforms

• Debian 13 Trixie

  • Qt 6.8.2
  • SQLCipher 4.6.1
  • Also requires qt6-base-private-dev for Qt's private headers.

• Windows 11

  • Qt 6.10.0
  • hacked together

Deployment

Follow Qt's plugin deployment guide. In short, put the plugin at sqldrivers/libqsqlcipher.so relative to your executable.

Static linking

You can also build the plugin statically by passing -DSTATIC=ON to CMake. When you build your application which uses the static plugin, you'll need to include the line Q_IMPORT_PLUGIN(QSQLCipherDriverPlugin); in one of your source files and define QT_STATICPLUGIN at compile time. And link to the static plugin, of course.

Note that setting -DSTATIC=ON only builds this plugin as a static library. If you also want to link to static versions of Qt and/or SQLCipher, it's up to you to make sure CMake finds static versions of those libraries.

Tests

Some basic tests are included - run make test. Note that while pretty much any C++ compiler can build the actual plugin, the tests require support for C++17. If you have an old compiler you can pass -DBUILD_TESTING=OFF to CMake to skip building the tests.
