QXmpp OMEMO module ================== The QXmpp OMEMO module adds support for OMEMO (v0.8+) end-to-end encryption by providing the `QXmppOmemoManager`. Dependencies ------------ * [QCA (Qt Cryptographic Architecture)](https://invent.kde.org/libraries/qca) * [libomemo-c](https://github.com/dino/libomemo-c) (built with `-DBUILD_SHARED_LIBS=ON`) Building -------- By default QXmpp is built without the OMEMO module. To enable it you need to provide `-DBUILD_OMEMO=ON` to cmake: cmake -DBUILD_OMEMO=ON Usage ----- QXmpp OMEMO is available as a CMake module. You can use it like this: ```cmake find_package(QXmpp COMPONENTS Omemo) target_link_libraries(${PROJECT} PRIVATE QXmpp::QXmpp QXmpp::Omemo) ``` How to use the OMEMO Manager is explained in the code documentation. Licensing issues ---------------- QXmppOmemo itself is (like the core) licensed under LGPL-2.1-or-later. However, as of today it is linking to `libomemo-c` which uses GPL-3.0. *This means that the resulting binaries must be used under the terms of the **GPL-3.0**.* We might move to a different, more permissive OMEMO library in the future and in that case no relicensing would be necessary.
