Welcome to command line chat project [CMD CHAT]

What is this?

It is a console chat with message encryption.

How does it work?

All you need to do is run a web server and connect to it via a client.

Run

Create and activate a virtual environment in Python

pip install secured_console_chat

import asyncio 
import cmd_chat

if __name__ == '__main__':
    asyncio.run(cmd_chat.run())

Or (Windows)

Start server:

.\cmd_chat.bat serve localhost 5000 

Connect to server:

.\cmd_chat.bat connect localhost 5000 tyler

Or (Linux)

Start server:

python3 cmd_chat.py serve localhost 5000

Connect to server:

python3 cmd_chat.py connect localhost 5000 tyler

How does encryption work?

• The client generates a private key.
• The server generates a symmetric key.
• The client sends the public key to the server.
• The server encrypts the symmetric key and sends it to the client.
• The client encrypts the private key.
• After that, communication with the server occurs via the symmetric key.

Example

Known bugs

• Sometime WS just drop connection
• Client input message problem. To start input, you need to press enter first, only after that you got pop up with message. Tried to fix, but nothing worked.
