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).

Sous Debian « Stretch » 9.8 (distribution stable au 2019-03-07), les paquets wireguard{,-dkms,-modules} sont disponibles et installés (eux seuls) exclusivement depuis le dépôt unstable, en version 0.0.20190227-1.
