Hello Chris and Nathan,

We've been having fun testing ChatSecure and trying your methods of key
verification! I'm wondering if we can add a quicker way for key
verification, especially for group chats?

The SafeSlinger project been concentrating on improving the usability of
key exchange and verification methods. It would be great to collaborate
with your ChatSecure and KeySync projects.

We have a free key exchange library available from our SafeSlinger
research project which allows 2-10 local or remote users to quickly and
securely exchange and verify each other's keys over an untrusted server.
We use our key verification system in a simple secure chat app,
SafeSlinger messenger, as well as a developer preview tool called
SafeSlinger Exchange Demo.

github.com/SafeSlingerProject/SafeSlinger-AppEngine
<http://github.com/SafeSlingerProject/SafeSlinger-AppEngine>

If you're interested in our key exchange/verification model, we can fork
the ChatSecure repo, attempt to add SafeSlinger to your Verify
Fingerprint options and see what you think of it.

Cheers,
Mike
