WireGuard VPN Protocol

Modern lightweight VPN tunneling protocol built on state-of-the-art cryptography for speed and auditability.

Core Principles & Analysis

• Merged into the mainline Linux kernel in version 5.6 in 2020.
• Uses Curve25519 for key exchange and ChaCha20-Poly1305 for authenticated encryption.
• Its codebase of roughly 4,000 lines makes security auditing far easier than IPsec or OpenVPN.
