Google tilf\u00f8jet<\/a><\/noindex> kode med indbygget st\u00f8tte til VPN i den prim\u00e6re kodebase af Android WireGuard<\/a><\/noindex>. WireGuard-koden er blevet overf\u00f8rt til versionen af Linux-kernen 5.4<\/a><\/noindex>, der udvikles til den kommende udgivelse af Android 12, fra den prim\u00e6re Linux-kernel 5.6<\/a><\/noindex>, som oprindeligt var vedtaget<\/a><\/noindex> WireGuard. Kerneniveau st\u00f8tten til WireGuard er aktiveret som standard<\/a><\/noindex>. <\/p>\n

Indtil nu har udviklerne af WireGuard til Android tilbudt<\/a><\/noindex> en mobilapp, som allerede blev fjernet<\/a><\/noindex> af Google fra Google Play-butikken p\u00e5 grund af et link til donationssiden p\u00e5 projektets hjemmeside, som overtr\u00e5dte betalingsvilk\u00e5rene (donationer er betragtes som uacceptable, hvis de indsamles af en ikke-specifikt registreret nonprofitorganisation).<\/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> af de anvendte krypteringsmetoder. WireGuard anvender en koncept for routing baseret p\u00e5 krypteringsn\u00f8gler, hvilket indeb\u00e6rer, at der knyttes en privat n\u00f8gle til hver netv\u00e6rksgr\u00e6nseflade, og at der bruges \u00e5bne n\u00f8gler til etablering af forbindelsen.<\/p>\n

Udvekslingen af \u00e5bne n\u00f8gler til ops\u00e6tning af forbindelsen sker analogt med SSH. Til godkendelse af n\u00f8gler og forbindelser uden opstart af en separat daemon i brugerrummet anvendes 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
