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)
- 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 <qxmpp folder> -DBUILD_OMEMO=ON
Usage
QXmpp OMEMO is available as a CMake module. You can use it like this:
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.
