Loosely based on WhatsApp, written in Python, This is a TCP chat application. Allowing for high security in a language like Python!

• Deploying the server is very easy! As simple as running python3 server.py <ip> <port> and you have yourself a chat server all nice and ready to go! Just connect with your client!

• I choose to make an easily deployable chat server because those more security aware of us never believe apps like WhatsApp^TM that promise End-To-End Encryption (I am by no means saying they are lying. Just that you never really know.) so by deploying your own server and telling your friends to connect! You know for sure that your messages are safe from prying eyes.

• Bored Sixth Form Student looking for a challenge this was a great way to get exactly that.

• This project also gave me some experience in the cryptographic area of Computer Science

• The use of AES-256Bit makes the messages about as secure as they can be. Even if someone gets a hold of your message history they would need a quantum computer for it to be feasible to be cracked

• The server software itself uses SSL when it sends and receives messages, so they MiTM attacks are unfeasible in this instance.

• The client uses os.urandom to generate the AES key and Initialisation vector this uses the devices random generator which is considered cryptographically secure in many instances.
