Jabber Clients like Pidgin and Gajim support PGP encrypted messages.
I would love to see http://xmpp.org/extensions/xep-0027.html implemented.
PGP has three advantages over OTR:
- The recipient can be offline
- Encrypted Group Chat is possible with a bit work
The same fors for OTR.
I would love to see PGP support coming to Jitsi!
It is not something that's currently on our todo list but if someone
with enough experience would like to dedicate time for an
implementation we'd be happy to discuss the details.
