CryptoChat 💬🔐

Cryptochat is a project that allows two users to communicate securely via the command line interface (CLI).

• The server is implemented in Python with the socket module.
• A network sniffer is implemented to capture the packets sent and received and ensure that the data is properly encrypted.
• An authentication is required before accessing the server.

About 🥢

• Cryptochat uses the RSA algorithm to encrypt messages.
• All datas are stored into a SQLite database.
• All roles run on the same machine by default.
