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.
*** Bug 28056 has been marked as a duplicate of this bug. ***
Jitsi provides a good example of a ZRTP implementation, with ZRTP working for both SIP and XMPP/Jingle: http://jitsi.org/index.php/Documentation/ZrtpFAQ http://jitsi.org/index.php/Main/Features 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. Here are some links that could be helpful as a starting place.. ZRTP Protocol information.. http://en.wikipedia.org/wiki/ZRTP http://www.voip-info.org/wiki/view/ZRTP Other ZRTP Clients.. http://www.twinklephone.com/ https://jitsi.org/ Some ZRTP libraries.. http://www.gnutelephony.org/index.php/GNU_ZRTP http://www.icall.com/developers/open-zrtp
I started a bounty for the addition of ZRTP support to Telepathy. https://freedomsponsors.org/core/issue/464/support-end-to-end-encryption-and-authentication
Any news?
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
(In reply to daniel.scharon from comment #9) > regarding ZRTP there is also this GStreamer-plugin: > https://github.com/wernerd/gstzrtp Neat. Thank you for adding the link
