diorwave/cmd-chat — reverse-engineered prompt

Build me a Python terminal chat app like this repo describes. I want to run one command to host a chat room from my machine, then another person can connect from their terminal with my IP, a port, a username, and a shared password.

The important part is privacy. Messages should be end to end encrypted, the password should never be sent over the network, and nothing should be saved to disk. When people disconnect or close the terminal, keys and chat history should be gone from memory. The host can relay messages, but shouldn’t be able to read them unless they know the room password.

Please make it easy to install with a requirements file and simple commands like serve and connect. It should work on Python 3.8 or newer, support multiple people in the same room, show usernames clearly, and feel like a normal live terminal chat. Add basic tests and a short README with setup, Windows notes, and usage examples.
