Read the WIKI for deeper information.

mschat is a simple application that allows you:

create your own chat server using the server
connect to an existing server using the client

Source code for the project can be found here. Note that I've used a custom version of the pydispo module.

Encryption

Messages sent using mschat are encrypted using:

Diffie-Hellman key exchange method to generate a numeric key shared by server and client
PBKDF2 key derivation function to get a stronger key that can be used with encryption algorithms
Fernet to encrypt the message using the derived key

DISCLAIMER: encryption effectiveness is not guaranteed by any official standard.

Note for fellows developers

This application was developed to demonstrate and test the use of Python to create server applications and for this reason I didn't focus on code readability and efficiency. Sorry.
