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.
- 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.
