WireGuard is a modern VPN (Virtual Private Network) protocol known for its simplicity, efficiency, and security. Developed by Jason A. Donenfeld, WireGuard aims to provide faster speeds and better performance compared to traditional VPN protocols like OpenVPN and IPSec. It operates at the kernel level, making it lightweight and resource-efficient. WireGuard uses state-of-the-art cryptography, including Curve25519 for key exchange and ChaCha20 for encryption, ensuring robust security while maintaining simplicity in its codebase. Its design focuses on ease of deployment and management, with a streamlined configuration process and automatic reconnection features.
