# 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 (2018-10-10) et en userspace écrit en GO (en cours de migration en Rust) sur les autres plateformes (*BSD, OpenWRT, Android, Windows).
Pour Debian stable, « Stretch » 9.8 puis « Buster » 10.0, des paquets `wireguard{,-dkms,-modules}` sont installables depuis le dépôt `unstable` (uniquement). Les mises à jour y sont fréquentes, par exemple les versions disponibles au 2019-03-07 étaient les 0.0.20190227-1, celles disponibles au 2019-07-19 étaient les 0.0.20190702-1.
