Presentert<\/a><\/noindex> significant release of VPN WireGuard 1.0.0<\/a><\/noindex>, which marked the delivery of WireGuard components in the main kernel body Linux 5.6<\/a><\/noindex> and stabilization of development. The code included in the Linux kernel has passed<\/a><\/noindex> an additional security audit conducted by an independent firm specializing in such checks. The audit found no issues.<\/p>\n

Since WireGuard is now being developed in the main Linux kernel, a repository has been prepared for distributions and users who continue to use older versions of the kernel wireguard-linux-compat.git<\/a><\/noindex>. The repository includes backported WireGuard code and a compat.h layer to ensure compatibility with older kernels. It is noted that as long as there is developer capability and user demand, a separate version of the patches will be maintained operationally. In its current form, the separate WireGuard version can be used with kernels from Ubuntu 20.04<\/a><\/noindex> og Debian 10 \u00abBuster\u00bb<\/a><\/noindex>, and is also available as patches for Linux kernels 5.4<\/a><\/noindex> og 5.5<\/a><\/noindex>. Distributions using the latest kernels, such as Arch, Gentoo, and
\nFedora 32, will gain the ability to use WireGuard with the kernel update 5.6.<\/p>\n

The main development process is now carried out in the repository wireguard-linux.git<\/a><\/noindex>, which includes the entire Linux kernel tree with changes from the WireGuard project. Patches from this repository will be reviewed for inclusion in the main kernel and regularly merged into the net\/net-next branches. The development of user-space utilities and scripts, such as wg and wg-quick, is taking place in the repository wireguard-tools.git<\/a><\/noindex>, which can be used to create packages in distributions.<\/p>\n

La oss minne om at VPN WireGuard er implementert ved hjelp av moderne krypteringsteknikker, gir sv\u00e6rt h\u00f8y ytelse, er enkel \u00e5 bruke, uten kompliserte elementer, og har bevist seg i flere store implementeringer som h\u00e5ndterer store mengder trafikk. Prosjektet har v\u00e6rt i utvikling siden 2015, har gjennomg\u00e5tt revisjon og formell verifisering<\/a><\/noindex> av de anvendte krypteringsmetodene. St\u00f8tte for WireGuard er allerede integrert i NetworkManager og systemd, og patchene for kjernen inng\u00e5r i de grunnleggende distribusjonene Debian Unstable<\/a><\/noindex>, Mageia, Alpine, Arch, Gentoo, OpenWrt, NixOS, Subgraph<\/a><\/noindex> og ALT<\/a><\/noindex>.<\/p>\n

I WireGuard brukes konseptet med rutelegging basert p\u00e5 krypteringsn\u00f8kler, som inneb\u00e6rer tilknytning av en privat n\u00f8kkel til hvert nettverksgrensesnitt og bruk av \u00e5pne n\u00f8kler for kommunikasjon. Utveksling av \u00e5pne n\u00f8kler for \u00e5 etablere forbindelsen skjer p\u00e5 lignende m\u00e5te som SSH. For n\u00f8kkelutveksling og tilkobling uten \u00e5 starte en egen daemon i brukerrummet brukes mekanismen Noise_IK fra Noise Protocol Framework<\/a><\/noindex>, som ligner p\u00e5 opprettholdelse av authorized_keys i SSH. Dataoverf\u00f8ring skjer via innkapsling i UDP-pakker. St\u00f8tte for endring av IP-adressen til VPN-serveren (roaming) uten \u00e5 bryte forbindelsen med automatisk omkonfigurering av klienten er tilgjengelig.<\/p>\n

For kryptering blir utnyttet<\/a><\/noindex> str\u00f8mkryptering ChaCha20<\/a><\/noindex> og algoritme for meldingsautentisering (MAC) Poly1305<\/a><\/noindex>, utviklet av Daniel Bernstein (Daniel J. Bernstein<\/a><\/noindex>), Tanja Lange
\n(Tanja Lange) og Peter Schwabe (Peter Schwabe). ChaCha20 og Poly1305 markedsf\u00f8res som raskere og sikrere alternativer til AES-256-CTR og HMAC, der programvareimplementasjonen tillater fast utf\u00f8relsestid uten spesialisert maskinvarest\u00f8tte. For generering av delt hemmelig n\u00f8kkel benyttes Diffie-Hellman-protokollen p\u00e5 elliptiske kurver i implementeringen Curve25519<\/a><\/noindex>, ogs\u00e5 foresl\u00e5tt av Daniel Bernstein. For hashing brukes algoritmen BLAKE2s (RFC7693)<\/a><\/noindex>. <\/p>\n

With the old testing<\/a><\/noindex> WireGuard har vist 3,9 ganger h\u00f8yere b\u00e5ndbredde og 3,8 ganger bedre respons sammenlignet med OpenVPN (256-bit AES med HMAC-SHA2-256). Sammenlignet med IPsec (256-bit ChaCha20+Poly1305 og AES-256-GCM-128) er det en liten ytelsefordel med WireGuard (13-18%) og lavere latenstid (21-23%). Testresultatene som er publisert p\u00e5 prosjektets nettsted dekker den eldre, isolerte implementeringen av WireGuard og er merket som utilstrekkelig. Siden testene ble gjennomf\u00f8rt har koden for WireGuard og IPsec blitt ytterligere optimalisert og fungerer n\u00e5 raskere. En mer omfattende testing som dekker den innebygde implementeringen i kjernen har ikke blitt utf\u00f8rt enn\u00e5. Det bemerkes imidlertid at WireGuard i visse situasjoner fortsatt overg\u00e5r IPsec p\u00e5 grunn av multitr\u00e5ding, mens OpenVPN fortsatt er veldig sakte.<\/p>\n
