WireGuard: VPN without the complexity

WireGuard reimagines VPN with a radically minimal design: ~4,000 lines of code (vs 70,000 for OpenVPN), built into the Linux kernel, and using modern cryptography (ChaCha20, Curve25519, BLAKE2) with no algorithm negotiation or state machine to exploit.

Configuration is two lines: your private key and a list of peers with their public keys and allowed IPs. That's it.
