🔥 Torrentium

Direct peer-to-peer file sharing that works through firewalls!

Torrentium is a WebRTC-based P2P file sharing application that allows direct file transfer between two computers without requiring port forwarding, VPN setup, or cloud services.

✨ Features

• 🚀 Direct P2P Connection - Files transfer directly between computers
• 🔒 No Port Forwarding - Works through NAT and firewalls automatically
• 🔐 Encrypted Transfers - All data is encrypted by WebRTC
• 🌍 Works Anywhere - Mobile data, corporate networks, home WiFi
• 📱 Simple Setup - Just copy-paste two JSON strings
• ⚡ Fast Transfer - Direct connection, no intermediary servers

🚀 Quick Start

1. Build and Run

go build
./torrentium

2. Connection Setup

Person A (Initiator):

> offer
[Copy the generated offer JSON]

Person B (Responder):

> answer <paste_offer_json_here>
[Copy the generated answer JSON]

Person A (Complete):

> complete <paste_answer_json_here>
✅ Connection established!

3. Transfer Files

Either person can now request files:

> download filename.txt

📋 Commands

• offer - Create connection offer (start here)
• answer <offer> - Answer connection offer
• complete <answer> - Complete connection with answer
• download <file> - Download file from peer
• status - Show connection status
• help - Show instructions
• exit - Quit application

🔧 Requirements

• Go 1.21 or later
• Internet connection (for initial WebRTC signaling)
• Files to share in the same directory

🌐 How It Works

Torrentium uses WebRTC technology to establish direct peer-to-peer connections:

1. Signaling Phase: Peers exchange connection information (offer/answer)
2. NAT Traversal: WebRTC automatically handles firewall/NAT issues using STUN servers
3. Direct Connection: Once established, files transfer directly between computers
4. Encrypted Transfer: All data is automatically encrypted by WebRTC

🛠️ Building from Source

git clone <repository-url>
cd torrentium
go mod tidy
go build

📝 Notes

• Downloaded files are saved with downloaded_ prefix
• Both computers need internet access for initial connection setup
• After connection is established, transfer works even on local networks
• Works on Windows, Linux, and macOS
