[talk] encrypted chat server?

[Isaac (.ike) Levy]

Hey All,

It's been a *long* time since I've run an IRC server, but I want to run
a chat server again.

I'm looking to do it with some form of end to end crypto, (I don't care
if the server itself does tls etc...), so I know client end tools are
probably the more important thing I should dig into looking at. 
(Including iOS/Android apps.)

- What's the state of the art for simple encrypted chat?
- Any OTR users in the house who can point me at an overview of the
state of that tooling?
- Is there any way to use good old IRC for transport, or is XMPP really
the thing?

This is obviously not good for iOS/Android use, but PGP integration is
cool, but I'd REALLY like to know if there is any chat tooling which
could leverage SSH public keys?  (Already a culture my peeps understand
how to manage ver well...)

On the server end, I'm obviously looking for a clean/reliable solution...

Best,
