I use OTR[1], works with irssi and pidgin (maybe all libpurple clients?). For voice I recently saw a reference to Jitsi[2] here on HN. So I have no experience

I use OTR[1], works with irssi and pidgin (maybe all libpurple clients?). For voice I recently saw a reference to Jitsi[2] here on HN. So I have no experience with it. [1] http://www.cypherpunks.ca/otr/ http://www.cypherpunks.ca/otr/ [2] https://jitsi.org/ https://jitsi.org/ Addendum: I went to give jitsi a try and was suprised to see that there are no signatures for any of the downloads. It does not seem that binary signatures are that important to the jitsi team. I took a peak inside the debian package and discovered that the repository signing key has no signatures on it. There is also an open bug to have signatures for the windows binary but that is also an open issue.
