ok guys, im having a little trouble diving into this, anyone wanna help?

ive got a server set up, and a client app. the client has a the server's public key built in, and encrypts the aes key/iv and sends it to the server, simple enough.

but now, after the first socket connection is over, what do i do? ive got both sides with the same aes key, but the server has multiple keys for other clients. so when the first client connects again, how do i know which key to use?

ive tried implementing a session class where there's a session id, but it doesnt work because the id must be encrypted, too. can someone help a fellow ranted out?
