My point was that if you are worried about people putting the effort in
to cracking *your* SSL based chats, then I would be wondering what you
were actually talking about. And if I was that concerned about it then I
would not be asking for advice like this on d-u (apologies to all
subscibers). I would be doing research in to how to actually acheive
some proper security, rather than using some attempts to add encryption
to existing protocels over public switched networks (no offence to those
who have added encryption capabilities to these protocols, capabilities
I use all the time and value a lot).

If you are just the paranoid type then SSL using something like
(man 1 ciphers) should put off the casual attacker.

I'm not sure what you mean by the other end of the communication? Are
you planning to be talking to people who don't use encryption? In that
case there is not a lot of point in worrying about how strong your
encryption is.
