🌊 BitTorrent Client Implementation

Hey! This is my BitTorrent client built during the Codecrafters challenge.

🚀 Features

• ✨ Parse .torrent files and extract metadata
• 🤝 Connect to peers using the BitTorrent protocol
• 📡 Communicate with trackers to discover peers
• 📦 Download pieces from multiple peers simultaneously
• ✅ Verify downloaded pieces using SHA1 hashing
• 📊 Basic download progress tracking

🛠️ Technical Implementation

This client implements core BitTorrent protocol features including:

• Bencode Parser: Custom implementation for encoding/decoding bencode format
• Peer Wire Protocol: Handles peer communication and piece exchange
• Tracker Communication: Manages tracker requests and peer discovery
• Piece Management: Downloads and verifies file pieces
• TCP Connections: Handles concurrent peer connections

Planned Features

• 🚄 Multi-threaded downloading for improved performance
• 📊 Real-time download progress visualization
• 🔄 Resume interrupted downloads
• 🎯 Selective file downloading from multi-file torrents
• 🔒 Support for encrypted peer connections
• 📱 Web UI for remote management
• 💾 Configurable download queue management
• 🌡️ Bandwidth throttling and scheduling
• 🔍 DHT (Distributed Hash Table) support for trackerless torrents
