We use AES-256 symetric encryption. The key must be stored in the project's parent directory in a file named 'key' (default). You can change this setting by editing this line.
The server decrypts the messages on the fly to check whether it is a client request. The messages are then stored encrypted. The server has a buffer of 30 messages.
The client uses a configuration file client.cfg which must be of the form 'pseudo,ipv4_address,port'. The client consists of two parts, since we won't do any GUI (command line rules).
client_display.py is used to display the messages stored in the server.
To do so you must send !refresh.
client_send.py is used to send messages. Just type in what you want to say. There are excluded caracters: çèüéöàä£.
