Il driver \u00abwg\u00bb con supporto per il protocollo WireGuard \u00e8 stato trasferito da FreeBSD, mentre il codice delle funzioni crittografiche, dell'interfaccia di rete e dell'API ioctl (per la gestione dallo spazio utente) \u00e8 stato preso in prestito 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, ad integrare il supporto per WireGuard.      <\/p>\n<p>In WireGuard viene applicato il concetto di routing basato su chiavi di crittografia, che implica l'associazione di una chiave privata a ciascuna interfaccia di rete e l'uso di chiavi pubbliche per l'interconnessione. Per l'accordo delle chiavi e la connessione senza l'esecuzione di un demone separato nello spazio utente \u00e8 stato utilizzato il meccanismo Noise_IK dal Noise Protocol Framework, simile al mantenimento di authorized_keys in SSH. La trasmissione dei dati avviene tramite incapsulamento in pacchetti UDP. \u00c8 supportato il cambio dell'indirizzo IP <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/vpn\/\"   title=\"VPN\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"115\">VPN<\/a>- del server (roaming) senza interruzione della connessione con riconfigurazione automatica del client.     <\/p>\n<p>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 presentati come alternative pi\u00f9 veloci e sicure rispetto ad AES-256-CTR e HMAC, la cui implementazione software consente di ottenere tempi di esecuzione fissi senza l'uso di supporto hardware speciale. Per la generazione della chiave segreta condivisa viene applicato il protocollo di Diffie-Hellman su curve ellittiche nella implementazione Curve25519, anch'essa proposta da Daniel Bernstein. Per l'hashing viene utilizzato l'algoritmo BLAKE2s (RFC7693).               <\/p>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
