# 🌊 BitTorrent Client Implementation

Hey! This is my BitTorrent client built during the [Codecrafters](https://codecrafters.io/) challenge. 

[![progress-banner](https://backend.codecrafters.io/progress/bittorrent/9bfe2f08-b35d-49aa-86d3-32c54792e640)](https://app.codecrafters.io/users/codecrafters-bot?r=2qF)

## 🚀 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
