P2P Chat and File Sharing Application 🚀

Demo.P2P.mp4

Overview

This project is a peer-to-peer (P2P) messaging and file sharing application written in C for Windows using Winsock2. It enables multiple peers to communicate by sending text messages and transferring files by splitting them into chunks. The application uses ephemeral ports for outgoing connections.

Features

💬 Text Messaging

• Send & Receive Messages: Communicate effortlessly with peers by sending text messages.

🔍 Query Active Peers

• Active Peer List: Retrieve a list of all peers that have interacted with your port.

❌ Exit from Network

• Graceful Disconnect: On exit, notify all connected peers and remove your port from their active peers list for a clean shutdown.

Bonus Features

🌟 Connect to Active Peers (Broadcast)

• Broadcast Messaging: Send a broadcast message to all active peers. Once received, these peers add your connection to their local peer list, expanding your network.

  

📁 File Transfer

• Large File Sharing: Transfer files between peers by splitting them into chunks, enabling support for large file sizes without overwhelming the network.
