ChaTerminal 0.1.0

A terminal-based encrypted chat system for LAN and remote connections

ChaTerminal

ChaTerminal is a cross-platform terminal-based encrypted chat system built with Python. It supports multiple users on a local network or via tunneling tools like Ngrok or LocalXpose, providing a lightweight and interactive chat experience — right from the terminal.

Features

• Encrypted communication using custom crypto utilities
• Multi-user chat over LAN or tunneled internet
• Color-coded messages with timestamp formatting
• Auto-complete for commands via readline and TAB
• Direct messaging using /dm <user> <message>
• Username renaming with /rename <new_name>
• List online users using /list
• Admin controls: /kick <user> (admin-only)
• Emote support: /me <action>
• Help menu: /help displays command reference
• User join/leave notifications
• Sound alert for DMs and admin actions
• Graceful client disconnect and server feedback
• Color personalization based on username hash

Getting Started

Requirements

• Python 3.9+
• pip packages: colorama, pyfiglet, readline (Linux/macOS), pyreadline3 (Windows)

Installation

pip install ChaTerminal

Running the Server

ChaTerminal init server

• Enter a port (e.g., 5555) and the admin username
• Displays local IP with instructions for LAN or tunneled access

Running the Client

In a new terminal window:

ChaTerminal init client

• Enter the server IP, port, and a unique username

Commands

Command	Description
/dm <user> <msg>	Send a private message
/kick <user>	Kick a user (admin only)
/list	View online users
/rename <name>	Change your username
/me <action>	Send an action/emote (e.g., waves)
/help	Show all available commands

Networking Tips

To let others join:

• Local network: Share the IP and port printed on server start
• Ngrok: ngrok tcp <port>
• LocalXpose: ./lx tcp <port>
• Port Forwarding: Map the server's port on your router

Example

# Start server
$ ChaTerminal init server
Port: 5555
Admin Username: admin

# Start client
$ ChaTerminal init client
Server IP: 192.168.1.100
Server Port: 5555
Username: myname

Security Note

All messages are encrypted using the crypto_utils module before transmission. Ensure that this module uses secure encryption practices for production deployments.
