I'm a fan of TFC and ran across this hardware based ZRTP device for protecting encrypted SIP.

It uses full open hardware and open source FPGA for everything.

Any interest in working on encrypting voice next?

My conjecture is Tor and the serial link introduce too much latency and require too much bandwidth for real time audio/video calls. But it's nice to see there's a Python implementation for that, I might poke around if I find time at some point, thank you for sharing this!

Could just allow sending voice message as well

This is already possible: just send a recording created with the Source Computer as a file to the recipient.

not sure if very practical

It makes very little sense to write convenience features for TFC, as one of the core-features is its minimal code-base and thus ease of audit. Avoiding feature creep is thus a major consideration. Any feature is also a maintenance burden and there's currently no time to develop new features.

I'd argue it's in fact easier to record such messages using GUI tools as those allow easy editing of the track, support different codecs for compression etc.

Also, for in-line encrypted voice the ticket is about, JackPair is worth a look. It doesn't use datadiodes, but it's still a reduced TCB.

I like this project and all the informations sharing here :D

Users more interested in audio communications, as far as the great JackPair project seem now dead?, could also look at this open source project:
