So you can try to look for "RFB 3.3" at the beginning of the non-encrypted buffer to detect that it is the first one.

Ok, great, thank you very much.

I am looking at dsm plugin, but i cant figure out (well, i said looking, not studying...), how to detect if the buffer you are encrypting is the first buffer (send/received) on some connection?

Btw, some "subchannel" for internal messages would be nice...

I want to make safe protocol with synchrone encryption key exchange via asynchrone encryption algorythm, but ..khm.. i am afraid that plugin system doesnt allow something like that as before encryption "handshake" is needed that exchanges public keys generated on both sides and exchange of keys ...
