Razvija\u010di projekta NetBSD javili su<\/a><\/noindex> o uklju\u010divanju u glavni deo jezgra NetBSD drajvera wg s implementacijom protokola WireGuard. NetBSD je postala tre\u0107i operativni sistem nakon Linuxa i OpenBSD-a s integrisanom podr\u0161kom za WireGuard. Tako\u0111e su ponu\u0111ene prate\u0107e komande za pode\u0161avanje VPN-a \u2014 wg-keygen i wgconfig. U podrazumevanoj konfiguraciji jezgra (GENERIC) drajver trenutno nije aktiviran i zahteva eksplicitno navo\u0111enje u pode\u0161avanjima \u201epseudo-device wg\u201c.<\/p>\n

Dodatno se mo\u017ee istaknuti publikaciju<\/a><\/noindex> ispravnog a\u017euriranja paketa wireguard-tools 1.0.20200820, koji uklju\u010duje alate koji rade u korisni\u010dkom prostoru, kao \u0161to su wg i wg-quick. U novom izdanju vr\u0161ena je priprema IPC-a za predstoje\u0107u podr\u0161ku WireGuard-u u operativnom sistemu FreeBSD. Obezbe\u0111eno je razdvajanje specifi\u010dnog koda za razli\u010dite platforme u razli\u010dite datoteke. U unit datoteku za systemd dodata je podr\u0161ka za komandu \u201ereload\u201c, \u0161to omogu\u0107ava pokretanje konstrukcija poput \u201esystemctl reload wg-quick at wgnet0\u201c.<\/p>\n

Podsjetimo, VPN WireGuard implementiran je na temelju suvremenih metoda \u0161ifriranja, jam\u010di vrlo visoke performanse, jednostavan je za kori\u0161tenje, oslobo\u0111en komplikacija i dobro se pokazao u brojnim velikim implementacijama koje obra\u0111uju velike koli\u010dine prometa. Projekt se razvija od 2015. godine, pro\u0161ao je audite i formalnu verifikaciju<\/a><\/noindex> primijenjenih metoda \u0161ifriranja. Podr\u0161ka za WireGuard ve\u0107 je integrirana u NetworkManager i systemd, a zakrpe za jezgru uklju\u010dene su u osnovni sastav distribucija Debian Unstable<\/a><\/noindex>, Mageia, Alpine, Arch, Gentoo, OpenWrt, NixOS, Subgraph<\/a><\/noindex> i ALT<\/a><\/noindex>.<\/p>\n

U WireGuardu se primjenjuje koncept rutiranja prema \u0161ifrirnim klju\u010devima, koji podrazumijeva vezanje svakog mre\u017enog su\u010delja uz privatni klju\u010d i primjenu za povezivanje javnih klju\u010deva. Razmjena javnih klju\u010deva za uspostavljanje veze obavlja se po analognom principu s SSH. Za uskla\u0111ivanje klju\u010deva i povezivanje bez pokretanja posebnog demona u prostoru korisnika, koristi se mehanizam Noise_IK iz Noise Protocol Framework<\/a><\/noindex>, sli\u010dan odr\u017eavanju authorized_keys u SSH. Prijenos podataka odvija se putem enkapsulacije u UDP pakete. Podr\u017eava se promjena IP adrese VPN poslu\u017eitelja (roaming) bez prekida veze s automatskom ponovnom konfiguracijom klijenta.<\/p>\n

Za \u0161ifriranje koristi se<\/a><\/noindex> stream cipher ChaCha20<\/a><\/noindex> i algoritam za autentifikaciju poruka (MAC) Poly1305<\/a><\/noindex>, razvijeni od strane Daniela Bernsteina (Daniel J. Bernstein<\/a><\/noindex>), Tanje Lange
\n(Tanja Lange) i Petera Schwabea (Peter Schwabe). ChaCha20 i Poly1305 se predstavljaju kao br\u017ei i sigurniji analozi AES-256-CTR i HMAC, \u010dija softverska implementacija omogu\u0107uje postizanje fiksnog vremena izvr\u0161avanja bez kori\u0161tenja posebne hardverske podr\u0161ke. Za generiranje zajedni\u010dkog tajnog klju\u010da koristi se protokol Diffie-Hellman na elipti\u010dnim krivuljama u implementaciji Curve25519<\/a><\/noindex>, tako\u0111er predlo\u017een od strane Daniela Bernstein-a. Za hashiranje se koriste algoritmi BLAKE2s (RFC7693)<\/a><\/noindex>. <\/p>\n
