textsecure VS convergence-components

I can't vouch for it, but this looks worth checking out: https://github.com/signal-golang/textsecure

So I think we need a native Linux client. I do not think Axolotl is a viable long term solution because it uses its own implementation of the Signal network protocol (written in Go). Reimplementing the cryptography and network protocol is a ton of work and will continue to be a ton of work as upstream adds more features. Axolotl has only just started reimplementing the new Signal groups protocol which was introduced 5 months ago. Also, the security of a reimplementation is dubious.

Sailfish applications use Qt's QML declarative language for their GUI. Sailfish has a proprietary QML library in addition to the QML elements included in Qt (Qt Quick). What we need to do is decouple Whisperfish's QML from the Sailfish QML library (which is called Silica). Fortunately PureMaps has already done the same thing and made a QML library that abstracts over the QML libraries of Sailfish, KDE (Kirigami), and Ubuntu Touch.

There’s also this project to bring SailfishOS apps to other mobile Linux platforms https://gitlab.com/dylanvanassche/convergence-components that might be applicable here.
