OpenSSL 3.5 er klassificeret som en LTS-udgivelse med en supportperiode p\u00e5 5 \u00e5r (til april 2030). Supporten for de tidligere versioner OpenSSL 3.3, 3.2 og 3.0 LTS vil forts\u00e6tte indtil april 2026, november 2025 og september 2026 henholdsvis. Projektkoden distribueres under Apache 2.0-licensen.     <\/p>\n<p>Hovednyheder:   <\/p>\n<ul>\n<li class=\"l\"> Tilf\u00f8jet support for kryptografiske algoritmer, der er resistente over for angreb fra kvantecomputere:\n<ul>\n<li class=\"l\"> ML-KEM (CRYSTALS-Kyber) \u2014 en algoritme til n\u00f8gleudveksling, der bruger kryptografiske metoder baseret p\u00e5 l\u00f8sningen af opgaver fra gitterteori, hvis l\u00f8sningshastighed ikke adskiller sig p\u00e5 traditionelle og kvantecomputere.\n<li class=\"l\"> ML-DSA (CRYSTALS-Dilithium) \u2014 en algoritme til dannelse af digitale signaturer, der baserer sig p\u00e5 gitterteori.\n<li class=\"l\"> SLH-DSA (Sphincs+) \u2014 en algoritme til dannelse af digitale signaturer, der anvender kryptografiske metoder baseret p\u00e5 hash-funktioner. SLH-DSA er langsommere end ML-DSA og har st\u00f8rre signaturst\u00f8rrelse, men er baseret p\u00e5 helt forskellige matematiske principper, hvilket betyder, at den forbliver effektiv i tilf\u00e6lde af kompromittering af gitterteori-baserede algoritmer.   <\/ul>\n<li class=\"l\"> Fuld support for QUIC-protokollen (RFC 9000) er blevet implementeret, som nu er tilg\u00e6ngelig for b\u00e5de klient- og serverapplikationer. QUIC er et lag ovenp\u00e5 UDP-protokollen, der underst\u00f8tter multiplexing af flere forbindelser og tilbyder krypteringsmetoder, der svarer til TLS. QUIC-protokollen anvendes i HTTP\/3 og blev udviklet som et alternativ til TCP+TLS-kombinationen, der l\u00f8ser problemer med lang tid til etablering og forhandlig af forbindelser i TCP, samt fjerner forsinkelser ved pakkeudfald under dataoverf\u00f8rsel.\n<li class=\"l\"> Muligheden for at bruge tredjepartsstakke, der implementerer QUIC-protokollen, er blevet tilf\u00f8jet, herunder stakke, der underst\u00f8tter 0-RTT-tilstand (0 Round Trip Time), hvilket muligg\u00f8r straks at starte dataoverf\u00f8rsel efter sending af oprettelsespakken.\n<li class=\"l\"> Support for uigennemsigtige (opaque) objekter til symmetriske n\u00f8gler (EVP_SKEY), der skjuler detaljer om n\u00f8gleimplementering, er blevet tilf\u00f8jet.\n<li class=\"l\"> Tilf\u00f8jet parameteret \u00abno-tls-deprecated-ec\u00bb for at deaktivere underst\u00f8ttelse af TLS-grupper, der er erkl\u00e6ret for\u00e6ldede i RFC-8422.\n<li class=\"l\"> Tilf\u00f8jet parameteret \u00abenable-fips-jitter\u00bb, der aktiverer brugen af en jitter-baseret kilde til entropi i FIPS-provider. Entropi genereres ud fra m\u00e5ling af tidsforskelle ved gentagen udf\u00f8relse af et bestemt s\u00e6t instruktioner p\u00e5 CPU'en, som afh\u00e6nger af mange interne faktorer og er uforudsigelig uden fysisk kontrol over CPU'en.\n<li class=\"l\"> I CMP (Certificate Management Protocol) er der tilf\u00f8jet st\u00f8tte til centraliseret n\u00f8glegenerering (den offentlige og private n\u00f8gle til klienten genereres p\u00e5 serveren). <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3960\">server<\/a>).\n<li class=\"l\"> St\u00f8tte til at levere flere n\u00f8gles\u00e6t (keyshares) for \u00e9n TLS-forbindelse er tilf\u00f8jet.\n<li class=\"l\"> Et API til pipelining er tilf\u00f8jet, hvilket muligg\u00f8r samtidig behandling af flere datablokke ved brug af visse krypteringsmetoder som AES-GCM, der underst\u00f8tter parallelle beregninger.\n<li class=\"l\"> I applikationerne req, cms og smime er standard krypteringsalgoritmen \u00e6ndret fra des-ede3-cbc til aes-256-cbc.\n<li class=\"l\"> Hybridgrupperne KEM (Key Encapsulation Mechanism), der er modstandsdygtige over for kvanteangreb, er tilf\u00f8jet til standardcipherlisten for TLS og valgt som prioriterede.\n<li class=\"l\"> Algoritmerne X25519MLKEM768 og X25519 er tilf\u00f8jet til de n\u00f8gles\u00e6t (keyshares), der bruges som standard i TLS.\n<li class=\"l\"> Funktionerne BIO_meth_get_*() er erkl\u00e6ret for\u00e6ldede.        <\/ul>\n<p>Kilde: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63039\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 \u0431\u0438\u0431\u043b\u0438\u043e\u0442\u0435\u043a\u0438 OpenSSL 3.5.0 \u0441 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0435\u0439 \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u043e\u0432 SSL\/TLS \u0438 \u0440\u0430\u0437\u043b\u0438\u0447\u043d\u044b\u0445 \u0430\u043b\u0433\u043e\u0440\u0438\u0442\u043c\u043e\u0432 \u0448\u0438\u0444\u0440\u043e\u0432\u0430\u043d\u0438\u044f.
