greenfox

The Green Fox VPN protocol is a secure, fast, open-source, and free technology designed to protect privacy and data security on public networks using advanced encryption and decentralized technologies.

🦊 Features

Core VPN Features

• X25519 Key Exchange - Modern elliptic curve cryptography
• ChaCha20-Poly1305 - Fast, authenticated encryption
• TLS/WebSocket Camouflage - Evades Deep Packet Inspection (DPI)
• Anti-Censorship - Designed to bypass Iran's Antigravity blocking
• Serverless Compatible - Works on standard HTTP/HTTPS ports
• UDP Fallback - Direct UDP transport when TCP blocked

🔒 Leak Prevention (v3.0+)

Complete DNS & IP leak prevention:

• ✅ DNS Leak Protection - All DNS queries forced through VPN tunnel only
• ✅ IPv4 IP Leak Prevention - Strict killswitch blocks non-VPN traffic
• ✅ IPv6 Leak Prevention - IPv6 completely disabled
• ✅ WebRTC Leak Prevention - STUN/TURN servers blocked
• ✅ DNS Rebinding Protection - Private IP resolution blocked
• ✅ Split-Tunnel Prevention - Impossible to bypass VPN
• ✅ Leak Detection Tests - Built-in verification system

🌐 Decentralized P2P Mode (v4.0+ - NEW!)

Ethereum testnet-powered decentralized VPN:

• ✅ No Central Server - Nodes discovered via blockchain
• ✅ Trustless Network - Transparent node reputation on-chain
• ✅ Censorship Resistant - Can't be blocked or shut down
• ✅ P2P Architecture - Anyone can run a node instantly
• ✅ Completely Legal - Uses free testnet (no real money)

🚀 Quick Start

Traditional Centralized Mode

Start Server:

sudo python Protocol.py server --port 443 --tun tun0

Connect as Client:

sudo python Protocol.py client <SERVER_IP> <SERVER_PUB_HEX> --port 443

Decentralized P2P Mode (NEW!)

Run a VPN Node (auto-registers on blockchain):

sudo python Protocol.py server

Connect as Decentralized Client (auto-discovers nodes):

sudo python Protocol.py client-decentralized

List Available Nodes:

python Protocol.py discover-nodes
