Secure messaging

Once two different clients have successfully logged in, they can start communicating securely. Each of them must perform the following commands first:

• .pk - obtain an RSA key pair and store it in memory (key pair is generated if not exists).
• .pe id - send public key to another peer with id specified.

Then some of peers could ask for secure communication with another peer typing the command:

• .pr id - ask for secure communication to peer with id

Another peer could accept or reject an incoming request:

• .pc id - accept request from peer with id and start secure communication.
• .pd id - reject request from peer with id. Communicate without encryption.

Any peer could abort secure communication at any time:

• .px id - abort (or reject, if not previously accepted) secure communication.

Secure communication aborts automatically, when any of peers logs out or gets dropped from chat.
