CryptTunnel is a professional-grade, multi-threaded VPN-tunneling framework built in Python. It provides a secure, encrypted relay for client-server communication using AES-256 encryption.

Features

• End-to-End Encryption: Secured with cryptography.fernet (AES-256).
• Multi-threaded Architecture: Efficiently handles multiple concurrent clients.
• Robust Logging: Built-in observability for real-time traffic monitoring.
• Interactive Tunneling: Dynamic client-side input streaming.
• Secure Secret Management: Uses .env files for environment variables.
