Description Josh Triplett 2009-07-26 09:50:52 UTC
ZRTP provides end-to-end encryption of RTP, without using SIP or similar for negotiation or key exchange.  I'd love to see support for this in Telepathy, in a way that both SofiaSIP and Gabble can use.

GNU ZRTP and the libZRTP SDK both provide libraries implementing ZRTP.

Several other clients have support for ZRTP, such as Twinkle; these should interoperate with any other implementation of ZRTP.

I don't know if any client yet supports ZRTP for XMPP/Jingle calls; that would prove particularly useful.

Hi.

Is this already in progress? Would be required for many things, e.g. https://bugzilla.gnome.org/show_bug.cgi?id=589778

Cheers,
Chris.

Jitsi provides a good example of a ZRTP implementation, with ZRTP working for both SIP and XMPP/Jingle:

Some background information on this is here:
https://wiki.ubuntu.com/secureVOIP

There is also the nightlies of cSIPSIMPLE (https://code.google.com/p/csipsimple/), which implements ZRTP for SIP calls on Android.

I am really interested in this and would be prepared to throw a small amount of money at pushing it through the various stages required to get zRTP-secured XMPP/Jingle calls in Empathy. (At the moment I'm using Jitsi, which isn't anywhere near as nice to use as Empathy.)

From the many comments that I have seen around generally, I would expect others to be the same. Perhaps you could establish a BidForFix to have this feature implemented and see if people are interested in financing it?

I'm also very interested in this feature.

ZRTP has protection against main-in-the-middle attacks and is very easy to use.

I started a bounty for the addition of ZRTP support to Telepathy.

Any news?
Comment 8 daniel.scharon 2014-11-17 11:56:25 UTC
it's supported now within farstream: https://bugs.freedesktop.org/show_bug.cgi?id=52481

regarding ZRTP there is also this GStreamer-plugin: https://github.com/wernerd/gstzrtp
