Udviklerne af NetBSD-projektet meldte<\/a><\/noindex> om inkludering i hovedkernen af NetBSD-driveren wg med implementering af WireGuard-protokollen. NetBSD blev det tredje OS efter Linux og OpenBSD med integreret support for WireGuard. Derudover tilbydes tilh\u00f8rende kommandoer til ops\u00e6tning af VPN \u2014 wg-keygen og wgconfig. I standard kernkonfigurationen (GENERIC) er driveren endnu ikke aktiveret og kr\u00e6ver eksplicit angivelse i indstillingerne 'pseudo-device wg'.<\/p>\n

Yderligere kan det n\u00e6vnes publicering<\/a><\/noindex> rettende opdatering af wireguard-tools-pakken 1.0.20200820, der inkluderer brugerplads-v\u00e6rkt\u00f8jer som wg og wg-quick. I den nye udgave er IPC forberedt til den kommende support af WireGuard i operativsystemet FreeBSD. Koden er blevet opdelt i forskellige filer specifik til forskellige platforme. I unit-filen for systemd er der tilf\u00f8jet support for kommandoen 'reload', hvilket muligg\u00f8r at k\u00f8re konstruktioner som 'systemctl reload wg-quick at wgnet0'.<\/p>\n

Det er v\u00e6rd at bem\u00e6rke, at VPN WireGuard er baseret p\u00e5 moderne krypteringsmetoder, tilbyder meget h\u00f8j ydeevne, er nem at bruge, fri for komplekse funktioner og har vist sig effektiv i flere store implementeringer, der h\u00e5ndterer store m\u00e6ngder trafik. Projektet har v\u00e6ret under udvikling siden 2015, har gennemg\u00e5et revision og formel verifikation<\/a><\/noindex> anvendte krypteringsmetoder. St\u00f8tte til WireGuard er allerede integreret i NetworkManager og systemd, og patches til kernen indg\u00e5r i grundkomponenterne i distributioner Debian Unstable<\/a><\/noindex>, Mageia, Alpine, Arch, Gentoo, OpenWrt, NixOS, Subgraph<\/a><\/noindex> og ALT<\/a><\/noindex>.<\/p>\n

WireGuard anvender konceptet med n\u00f8glebaseret routing, som indeb\u00e6rer at tilknytte et privat n\u00f8gle til hver netv\u00e6rksgr\u00e6nseflade og anvende \u00e5bne n\u00f8gler til at etablere forbindelser. Udvekslingen af \u00e5bne n\u00f8gler til forbindelsesoprettelse foreg\u00e5r p\u00e5 lignende vis som SSH. Til aftale n\u00f8gler og forbindelser uden at starte en separat daemon i brugerland bruges Noise_IK-mekanismen fra Noise Protocol Framework<\/a><\/noindex>, der ligner vedligeholdelsen af authorized_keys i SSH. Dataoverf\u00f8rslen foreg\u00e5r ved inkapsulering i UDP-pakker. Skift af IP-adressen p\u00e5 VPN-serveren (roaming) underst\u00f8ttes uden afbrydelse af forbindelsen med automatisk genkonfiguration af klienten.<\/p>\n

Til kryptering kun 14,3% af webstederne i hele verden.<\/a><\/noindex> str\u00f8mcypher ChaCha20<\/a><\/noindex> og algoritme til autentificering af meddelelser (MAC) Poly1305<\/a><\/noindex>, udviklet af Daniel Bernstein (Daniel J. Bernstein<\/a><\/noindex>), Tanja Lange
\n(Tanja Lange) og Peter Schwabe. ChaCha20 og Poly1305 pr\u00e6senteres som hurtigere og sikrere alternativer til AES-256-CTR og HMAC, hvis softwareimplementering muligg\u00f8r en fast udf\u00f8relsestid uden at kr\u00e6ve s\u00e6rlig hardwareunderst\u00f8ttelse. Protokollen for at generere en delt hemmelig n\u00f8gle anvender Diffie-Hellman p\u00e5 elliptiske kurver i implementeringen Curve25519<\/a><\/noindex>, ogs\u00e5 foresl\u00e5et af Daniel Bernstein. Der anvendes algoritmen BLAKE2s (RFC7693)<\/a><\/noindex>. <\/p>\n
