OpenSSL 4.0 se clasifica como una versi\u00f3n con un ciclo de soporte normal, con actualizaciones lanzadas durante 13 meses. El soporte para versiones anteriores de OpenSSL 3.6, 3.5 LTS, 3.4 y 3.0 LTS continuar\u00e1 hasta noviembre de 2026, abril de 2030, octubre de 2026 y septiembre de 2026, respectivamente. El c\u00f3digo del proyecto se distribuye bajo la licencia Apache 2.0.     <\/p>\n<p>Novedades principales:   <\/p>\n<ul>\n<li class=\"l\"> Se agreg\u00f3 soporte para la extensi\u00f3n TLS ECH (Encrypted ClientHello, RFC 9849), destinada a cifrar la informaci\u00f3n sobre los par\u00e1metros de las sesiones TLS, como el nombre de dominio solicitado. A diferencia de la extensi\u00f3n ESNI (Encrypted Server Name Indication), en ECH se cifra todo el mensaje TLS ClientHello en lugar de cifrar a nivel de campos individuales, lo que permite bloquear filtraciones a trav\u00e9s de campos que no cubre ESNI, como el campo PSK (Pre-Shared Key).\n<li class=\"l\"> Se agreg\u00f3 soporte para ciertos algoritmos definidos en RFC 8998 que utilizan el conjunto de algoritmos criptogr\u00e1ficos SM2 normalizado en China: el algoritmo de firma digital sm2sig_sm3, el grupo de intercambio de claves curveSM2 y el grupo postcu\u00e1ntico curveSM2MLKEM768.\n<li class=\"l\"> Se agreg\u00f3 la funci\u00f3n criptogr\u00e1fica de hash cSHAKE, basada en el algoritmo SHA-3, que permite generar diferentes hashes a partir de los mismos datos de entrada para proteger contra ataques que manipulan la reutilizaci\u00f3n de datos.\n<li class=\"l\"> Se ha a\u00f1adido un algoritmo h\u00edbrido \u00abML-DSA-MU\u00bb, que combina el algoritmo postcu\u00e1ntico de generaci\u00f3n de firmas digitales ML-DSA (CRYSTALS-Dilithium) con la funci\u00f3n hash cl\u00e1sica SHAKE256.\n<li class=\"l\"> Se agreg\u00f3 soporte para las funciones de generaci\u00f3n de claves SNMP KDF basadas en HMAC-SHA y SRTP KDF basadas en AES-CM, utilizadas en protocolos de red SNMPv3 y SRTP para crear claves criptogr\u00e1ficas.\n<li class=\"l\"> Se ha a\u00f1adido la opci\u00f3n \u00ab-defer_tests\u00bb al comando \u00abopenssl fipsinstall\u00bb, que permite retrasar la ejecuci\u00f3n de pruebas al instalar m\u00f3dulos FIPS.\n<li class=\"l\"> Se implement\u00f3 soporte en la plataforma Windows para usar el enlace est\u00e1tico o din\u00e1mico con Visual C++ Runtime.\n<li class=\"l\"> Se agreg\u00f3 soporte en TLS 1.2 para la negociaci\u00f3n de intercambio de claves basada en el algoritmo FFDHE, de acuerdo con la RFC 7919.\n<li class=\"l\"> Se elimin\u00f3 el soporte para SSLv3 y SSLv2 Client Hello.\n<li class=\"l\"> Se elimin\u00f3 el soporte para motores cargables din\u00e1micamente, y en su lugar, para extender la funcionalidad de OpenSSL, se debe utilizar el concepto de proveedores conectables.\n<li class=\"l\"> En TLS, se ha deshabilitado el soporte para curvas el\u00edpticas obsoletas en la etapa de compilaci\u00f3n. Para restaurarlo, se puede usar la opci\u00f3n \u00abenable-tls-deprecated-ec\u00bb.\n<li class=\"l\"> Se ha eliminado la herramienta c_rehash, que ahora debe ser reemplazada por el comando \u00abopenssl rehash\u00bb.\n<li class=\"l\"> Se ha eliminado la opci\u00f3n obsoleta \u00abmsie-hack\u00bb del comando \u00abopenssl ca\u00bb.\n<li class=\"l\"> Se ha eliminado el soporte para los m\u00e9todos personalizados EVP_CIPHER, EVP_MD, EVP_PKEY y EVP_PKEY_ASN1.\n<li class=\"l\"> Se han eliminado las funciones obsoletas SSL\/TLS atadas a versiones fijas de los protocolos, como \u00abTLSv1_client_method()\u00bb.\n<li class=\"l\"> Se han eliminado las funciones obsoletas ERR_get_state(), ERR_remove_state() y ERR_remove_thread_state().\n<li class=\"l\"> Se ha detenido el soporte para las plataformas objetivo darwin-i386{,-cc} y darwin-ppc{,64}{,-cc}.  <\/ul>\n<p>Fuente: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65208\">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 4.0.0, \u043f\u0440\u0435\u0434\u043b\u0430\u0433\u0430\u044e\u0449\u0435\u0439 \u0441 \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u044e \u043f\u0440\u043e\u0442\u043e\u043a\u043e\u043b\u043e\u0432 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.
