WireGuard
A small, fast, modern tunnel built on fixed cryptography.
How widely is it used?
Among the most widely deployed options in 2026The most used VPN protocol today — in the Linux kernel and the default in most consumer apps and mesh products.
How it works
Each peer is identified by a Curve25519 public key. There is no cipher negotiation: ChaCha20-Poly1305, BLAKE2s and X25519 are fixed, which is why the implementation is a few thousand lines instead of hundreds of thousands.
