A complete corporate HTTP/HTTPS proxy developed in Rust, focused on security, control, and performance. This proxy is ideal for corporate environments that require authentication, content blocking, and traffic logging.

• 🔐 Authentication via Proxy-Authorization header (Basic Auth)
• 🌐 HTTPS support using the CONNECT method
• 🚫 Domain and keyword blocking (e.g., "porn", "torrent", etc.)
• 📄 External configuration via proxy_config.json
• 📦 Automatic fallback to default settings if JSON config is missing
• 🧾 Detailed request logging
• ⚡ Multithreaded and asynchronous with tokio

• Rust (version 1.70+ recommended)
• Cargo

Clone the repository and build the project:

git clone https://github.com/filipe-freitas-dev/https_proxy.git
cd https_proxy
cargo build --release

You can provide a proxy_config.json file with the following structure:

{
  "proxy_port": 8080,
  "username": "admin",
  "password": "supersecret",
  "blocked_domains": ["example.com", "test.org"],
  "blocked_keywords": ["porn", "torrent", "hack"]
}

If the file is not found, the proxy will use default settings:

{
  "proxy_port": 8080,
  "username": "admin",
  "password": "password",
  "blocked_domains": [],
  "blocked_keywords": []
}

With custom configuration:

./target/release/rust-corporate-proxy

Or directly with default settings:

cargo run --release

The proxy logs all processed requests:

• Authenticated and blocked requests
• Keyword detection
• Blocked domain access attempts
• TLS/connection errors

Example log:

{"timestamp":"2025-05-28T17:03:04.304297450Z","client_ip":"127.0.0.1","user":"admin","method":"GET","url":"http://detectportal.firefox.com/success.txt?ipv6","status":403,"blocked":true,"block_reason":"Domínio bloqueado","response_size":0}

• Persistent log storage
• Web dashboard for monitoring
• Dynamic blocking list via API
• Rate limiting

This proxy was developed as a practical project for studying cybersecurity, networking, and systems programming in Rust. It aims to deliver a robust and extensible tool for monitoring and controlling HTTP/HTTPS traffic in enterprise environments.
