- Host has listening TCPListener
- Client connects to Host's TCPListener
- Both sides prepare DecryptProviders
- Host writes Host's DecryptProvider's public key. Client Reads and prepares their EncryptProvider
- Client writes Client's DecryptProvider's public key. Host Reads and prepares their EncryptProvider
- Host writes own AES key. Client Recieves and sets as own AES, note AES is symetrical i.e no public/private key
- Encrypted communication can now begin
- Sender sends [0,1,2,3,4] in binary, which is the constant used to warn that an image is comming. Can be changed, just need's to be unwritable in utf-8
- Sender sends image size
- Sender sends image encrypted with AES instead of RSA
- Communications return to normal
- Save selected index.
- Clear list.
- Run through list of contacts and add them to the list. Check if nickname is set, else use suitable replacement
- Set selected index to last selected index.
