Collaborative Whiteboard

This project consists of a client-server architecture enabling multiple clients to collaborate on a shared whiteboard in real-time using Python's sockets and SSL/TLS encryption. The server side manages client connections, handles client activity, and broadcasts drawing commands to all connected clients. The client side provides a graphical user interface (GUI) built with Tkinter, allowing users to draw, select colors, adjust brush thickness, and perform undo and redo actions.

Features:

Secure Communication: SSL/TLS encryption ensures secure communication between the server and clients, protecting data integrity and confidentiality.
Real-time Collaboration: Clients can draw simultaneously on a shared whiteboard, with changes/edits instantly propagated to all connected clients.
Clear/Undo/Redo Functionality: Users can easily erase the entire canvas or undo/redo individual drawing actions to correct mistakes or revert changes.
Color Selection and Brush Thickness: Interactive color picker and adjustable brush thickness enhance drawing capabilities and user experience.
Client Disconnect Handling: The server gracefully handles client disconnections and removes inactive clients from the active client list.

Commands:

In one terminal/window: python ssl_server.py
In another terminal/window: python ssl_client.py
