[Tutor] SHA256 P2P Chat in python

[Lukas Nemec]

Hi,

I did a similar thing recently, a chat, that encrypts and signs (for 
authenticity) each message sent with private-pub keypair: 
https://github.com/lunemec/python-chat.

It is not p2p, it sends messages to server, which decrypts them, 
encrypts with its pubkey and sends to all clients for decoding.

It is just a prototype and could be done better. I wanted to have the 
server act only as a relay for clients to discover each other (no need 
for DHT) and then to forward each client's pubkey to all others.

I'm not sure exactly how onion routing would be done, I suppose 
something similar to Tor, but how would you want to use it on chat?
