HTTP Forward Proxy

A C++ HTTP forward proxy server that routes traffic through multiple hops for anonymous communication. Currently implementing multi-hop encryption similar to Tor's onion routing.

Current Status

Phase 1-2 Complete:

• Basic HTTP server with GET/POST request handling
• Single-hop proxy forwarding
• Multi-hop proxy chain routing (Proxy A → Proxy B → Destination)

Phase 3 In Progress:

• AES symmetric encryption between proxy nodes
• RSA public key cryptography for key exchange
• Layered encryption/decryption at each hop

Features

• Multi-hop forwarding: Route traffic through multiple proxy nodes
• Socket-based networking: Built with native C++ sockets
• HTTP request/response parsing: Full HTTP protocol support
• Modular architecture: Separate components for server, proxy, and utilities

Quick Start

# Build
make

# Run proxy server
./http_proxy

Architecture

Client → Proxy Node 1 → Proxy Node 2 → Destination Server
         (encrypt)      (decrypt/      (serve content)
                        re-encrypt)

Each proxy node decrypts the layer intended for it and forwards the remaining encrypted traffic to the next hop.

Roadmap

• HTTP server with static file serving
• Single-hop proxy forwarding
• Multi-hop proxy chain
• AES-256 encryption between nodes
• Onion routing with layered encryption
• SOCKS5 protocol support

Tech Stack

• Language: C++
• Networking: BSD sockets
• Encryption: OpenSSL (in progress)

Use Case

Building a Tor-like anonymous communication system where traffic is encrypted in layers and routed through multiple proxy nodes to ensure privacy and anonymity.
