Add user as friend from chat

If you are chatting with some random person, sometimes you may find that you know them, or perhaps, in a temporary fit of insanity, decide to trust this random stranger. There should be a button for this type of situation where you can click, and a message will pop up on their screen asking permission, and then you both are friends. It would have to send the .cryptic6 file though the network encrypted somehow, so that no one else could see the IP's, e.t.c..
