# Wireguard

Le VPN Kiss, utilisant les dernières règles de l'art, construit pour être audité & performant ! au revoir IPSec & OpenVPN !

Dans le Kernel Linux via DKMS pour l'instant (10/10/18) et en userspace écrit en GO (en cours de migration en Rust) sur les autres plateformes (*BSD, OpenWRT, Android, Windows).
