Description Dennis Schridde 2016-02-21 19:01:25 UTC
It would be nice if Telepathy would support the Axolotl protocol (Signal messenger, formerly TextSecure).

There are currently three implementations, for Android, iOS and Google Chrome:
* https://github.com/WhisperSystems/Signal-Android
* https://github.com/WhisperSystems/Signal-iOS
* https://github.com/WhisperSystems/Signal-Desktop

An implementation of the underlying protocol is available via the libaxolotl-c library:
* https://github.com/WhisperSystems/libaxolotl-c

The Java library contains more documentation:
* https://github.com/whispersystems/libaxolotl-java

The wire protocol is described here:
* https://github.com/WhisperSystems/Signal-Android/wiki/ProtocolV2

And the specs are available here:
* https://github.com/trevp/axolotl/wiki

Yes, Signal protocol be nice as would OMEMO. The only end-to-end crypto support currently in telepathy is a component of KDE-Telepathy that provides an OTR proxy between incoming messages and the chat widget.

I suspect it might be possible to add additional algorithms there.

Though there's also some additional work needed before the proxy could help Empathy.

Unfortunately I don't believe the few people still contributing to telepathy or its clients have the time to work on this.
