Projektet NetBSDs utvecklare rapporterade<\/a><\/noindex> Om inkluderandet av k\u00e4rnan i NetBSD av drivrutinen wg med implementering av WireGuard-protokollet. NetBSD har blivit det tredje operativsystemet efter Linux och OpenBSD med integrerat st\u00f6d f\u00f6r WireGuard. Dessutom erbjuds relaterade kommandon f\u00f6r att konfigurera VPN \u2014 wg-keygen och wgconfig. I standard k\u00e4rnkonfigurationen (GENERIC) \u00e4r drivrutinen f\u00f6r n\u00e4rvarande inte aktiverad och kr\u00e4ver explicit angivelse i inst\u00e4llningarna 'pseudo-device wg'.<\/p>\n

Dessutom kan det n\u00e4mnas publiceringen<\/a><\/noindex> Korrigerande uppdatering av paketet wireguard-tools 1.0.20200820, som inkluderar anv\u00e4ndarutrymmesverktyg som wg och wg-quick. I den nya versionen har IPC f\u00f6rberetts f\u00f6r det kommande st\u00f6det f\u00f6r WireGuard i operativsystemet FreeBSD. Koden som \u00e4r specifik f\u00f6r olika plattformar har separerats i olika filer. I unit-filen f\u00f6r systemd har st\u00f6d f\u00f6r kommandot 'reload' lagts till, vilket g\u00f6r det m\u00f6jligt att k\u00f6ra konstruktioner som 'systemctl reload wg-quick at wgnet0'.<\/p>\n

Vi p\u00e5minner om att VPN WireGuard bygger p\u00e5 moderna krypteringsmetoder, erbjuder mycket h\u00f6g prestanda, \u00e4r l\u00e4tt att anv\u00e4nda, utan komplikationer och har visat sig vara p\u00e5litlig i flera stora implementeringar som hanterar stora trafikvolymer. Projektet har utvecklats sedan 2015, har genomg\u00e5tt revision och formell verifiering<\/a><\/noindex> av de till\u00e4mpade krypteringsmetoderna. St\u00f6det f\u00f6r WireGuard \u00e4r redan integrerat i NetworkManager och systemd, och patcharna f\u00f6r k\u00e4rnan ing\u00e5r i de grundl\u00e4ggande distributionerna Debian Unstable<\/a><\/noindex>, Mageia, Alpine, Arch, Gentoo, OpenWrt, NixOS, Subgraph<\/a><\/noindex> och ALT<\/a><\/noindex>.<\/p>\n

I WireGuard till\u00e4mpas en koncept av nyckelbaserad rutning, vilket inneb\u00e4r att varje n\u00e4tverksgr\u00e4nssnitt kopplas till en privat nyckel och anv\u00e4nds f\u00f6r att l\u00e4nka offentliga nycklar. Utbytet av offentliga nycklar f\u00f6r att etablera en anslutning sker p\u00e5 liknande s\u00e4tt som med SSH. F\u00f6r att samordna nycklar och anslutning utan att starta en separat daemon i anv\u00e4ndarutrymmet anv\u00e4nds Noise_IK-mekanik. Noise Protocol Framework<\/a><\/noindex>, liknande bevarandet av authorized_keys i SSH. Datatransmission sker genom inkapsling i UDP-paket. St\u00f6d f\u00f6r att byta IP-adress p\u00e5 VPN-servern (roaming) utan att bryta anslutningen med automatisk omkonfigurering av klienten.<\/p>\n

F\u00f6r kryptering funktionen unix_crypt, som tar emot det l\u00f6senord som anv\u00e4ndaren anger utan att utf\u00f6ra escape av specialtecken. I git-repositoriet<\/a><\/noindex> str\u00f6mmande krypteringsmetod ChaCha20<\/a><\/noindex> och meddelandeautentiseringsalgoritm (MAC) Poly1305<\/a><\/noindex>, utvecklade av Daniel Bernstein (Daniel J. Bernstein<\/a><\/noindex>), Tanja Lange
\n(Tanja Lange) och Peter Schwabe (Peter Schwabe). ChaCha20 och Poly1305 positioneras som snabbare och s\u00e4krare alternativ till AES-256-CTR och HMAC, vars programvaruimplementation m\u00f6jligg\u00f6r en fast k\u00f6rningstid utan att s\u00e4rskild h\u00e5rdvarust\u00f6d kr\u00e4vs. F\u00f6r att generera en gemensam hemlig nyckel anv\u00e4nds protokollet Diffie-Hellman p\u00e5 elliptiska kurvor i implementationen Curve25519<\/a><\/noindex>, ocks\u00e5 f\u00f6reslagen av Daniel Bernstein. F\u00f6r hashing anv\u00e4nds algoritmen BLAKE2s (RFC7693)<\/a><\/noindex>. <\/p>\n
