Il kernel del sistema operativo DragonFly BSD ha ricevuto circa 100 modifiche per implementare il supporto per VPN WireGuard. Il driver \u00abwg\u00bb con supporto per il protocollo WireGuard \u00e8 stato portato da FreeBSD, mentre il codice delle funzioni crittografiche, dell'interfaccia di rete e dell'API ioctl (per la gestione dallo spazio utente) \u00e8 stato derivato da OpenBSD. Le modifiche all'utilit\u00e0 ifconfig, necessarie per configurare la VPN, sono state trasferite da OpenBSD. L'implementazione \u00e8 compatibile con tutti i client ufficiali di WireGuard per Linux, Windows, macOS, *BSD, iOS e Android. DragonFly BSD \u00e8 diventato il quinto sistema operativo open source, dopo Linux, OpenBSD, NetBSD e FreeBSD, a integrare il supporto per WireGuard. <\/p>\n

WireGuard utilizza il concetto di instradamento basato su chiavi di crittografia, il quale implica l'associazione di una chiave privata a ciascuna interfaccia di rete e l'uso di chiavi pubbliche per la connessione. Per la negoziazione delle chiavi e la connessione senza l'avvio di un demone separato nello spazio utente, viene impiegato il meccanismo Noise_IK del Noise Protocol Framework, simile al mantenimento di authorized_keys in SSH. Il trasferimento dei dati avviene tramite incapsulamento in pacchetti UDP. \u00c8 supportato il cambio di indirizzo IP. VPN<\/a>-server (roaming) senza interruzione della connessione con riconfigurazione automatica del client. <\/p>\n

Per la crittografia, viene utilizzato il cifrario a flusso ChaCha20 e l'algoritmo di autenticazione dei messaggi (MAC) Poly1305, sviluppati da Daniel Bernstein, Tanja Lange e Peter Schwabe. ChaCha20 e Poly1305 sono posizionati come alternative pi\u00f9 veloci e sicure a AES-256-CTR e HMAC, la cui implementazione software consente di raggiungere un tempo di esecuzione fisso senza richiedere supporto hardware speciale. Per generare la chiave segreta condivisa, viene utilizzato il protocollo Diffie-Hellman su curve ellittiche nell'implementazione Curve25519, anch'essa proposta da Daniel Bernstein. Per l'hashing viene utilizzato l'algoritmo BLAKE2s (RFC7693). <\/p>\n
