It use Noise protocol framework, Curve25519, ChaCha20, Poly1305, BLAKE2, SipHash24 and HKDF.

• WireGuard is invisible to illegitimate peers and network scanners
• WireGuard uses only UDP protocol (port 41414).
• Connection-less protocol

• Curve25519 used for identified peers, using their public key, a 32-byte Curve25519 point

• sudo apt install wireguard

Included in March 2020 into the Linux Kernel 5.6 , available in Ubuntu since Ubuntu 20.10

• NordVPN offers NordLynx built on WireGuard

WireGuard's encryption speed claims to be faster that IPsec group protocols.
