OpenSSL 4.0 \u00e8 considerato una versione con supporto regolare, con aggiornamenti rilasciati per un periodo di 13 mesi. Il supporto per le versioni precedenti OpenSSL 3.6, 3.5 LTS, 3.4 e 3.0 LTS continuer\u00e0 fino a novembre 2026, aprile 2030, ottobre 2026 e settembre 2026, rispettivamente.

A differenza dell'estensione ESNI (Encrypted Server Name Indication), nell'ECH viene crittografato l'intero messaggio TLS ClientHello, consentendo di bloccare le perdite attraverso campi non coperti dall'ESNI, ad esempio il campo PSK (Pre-Shared Key).\n<li class=\"l\"> \u00c8 stato aggiunto il supporto per determinati algoritmi definiti nella RFC 8998, che utilizzano un insieme di algoritmi crittografici standardizzati in Cina: l'algoritmo di generazione della firma digitale sm2sig_sm3, il gruppo di scambio delle chiavi curveSM2 e il gruppo post-quantistico curveSM2MLKEM768.\n<li class=\"l\"> \u00c8 stata aggiunta una funzione crittografica di hashing cSHAKE, basata sull'algoritmo SHA-3, che consente di generare hash diversi a partire dagli stessi dati di input per proteggere contro attacchi che manipolano il riutilizzo dei dati.\n<li class=\"l\"> \u00c8 stato aggiunto l'algoritmo ibrido \u00abML-DSA-MU\u00bb, che combina l'algoritmo post-quantistico di firma digitale ML-DSA (CRYSTALS-Dilithium) con la classica funzione hash SHAKE256.\n<li class=\"l\"> \u00c8 stata aggiunta la supporto per le funzioni di generazione delle chiavi SNMP KDF basate su HMAC-SHA e SRTP KDF basate su AES-CM, utilizzate nei protocolli di rete SNMPv3 e SRTP per la creazione di chiavi crittografiche.\n<li class=\"l\"> Nel comando \u00abopenssl fipsinstall\u00bb \u00e8 stata aggiunta l'opzione \u00ab-defer_tests\u00bb, che consente di ritardare l'esecuzione dei test durante l'installazione dei moduli FIPS.\n<li class=\"l\"> Per la piattaforma Windows \u00e8 stata implementata la supporto per utilizzare il collegamento statico o dinamico con il Visual C++ Runtime.\n<li class=\"l\"> In TLS 1.2 \u00e8 stata aggiunta la supporto per la negoziazione dello scambio di chiavi basata sull'algoritmo FFDHE, conforme a RFC 7919.\n<li class=\"l\"> \u00c8 stata interrotta la supporto per SSLv3 e SSLv2 Client Hello.\n<li class=\"l\"> \u00c8 stata rimossa la supporto per i motori caricati dinamicamente, a cui si pu\u00f2 accedere utilizzando la concettualizzazione dei provider plug-in per estendere le funzionalit\u00e0 di OpenSSL.\n<li class=\"l\"> In TLS, durante la fase di compilazione, \u00e8 stata disabilitata la supporto per le curve ellittiche obsolete.
