BitForge - A Basic Torrent-like Client

BitForge is a custom-built torrent-like peer-to-peer (P2P) file sharing client designed from scratch in Python. It supports downloading files in parallel from multiple peers, seeding, and a GUI interface using PyQt5.

BitForge was inspired by the inner workings of the original BitTorrent protocol. The goal was to demystify how P2P file-sharing systems operate under the hood by rebuilding the entire process—from chunked file transfer to tracker registration and multi-peer discovery—entirely in Python.

This project serves as a hands-on implementation for learning about:

• Networking and sockets
• Multi-threaded file transfer
• Hash-based chunk verification
• Torrent protocol mechanics
• GUI development with PyQt5

• 📁 .torrent file parsing (bencode decoding)
• 🌐 Tracker-based peer discovery
• ⬇️ Multi-peer parallel chunk downloads
• 🧩 Resume support using JSON
• 💻 CLI seeding & uploading with seeding.py and my_server.py
• 🖥️ PyQt5 GUI interface with progress bar, chunk status, theme toggle, and logo branding
