Il progetto LibreSSL \u00e8 orientato a fornire un supporto di qualit\u00e0 per i protocolli SSL\/TLS, eliminando funzionalit\u00e0 superflue, aggiungendo ulteriori misure di protezione e conducendo una significativa pulizia e revisione della base di codice. L'uscita di LibreSSL 3.9.0 \u00e8 considerata sperimentale, nella quale si sviluppano funzionalit\u00e0 che entreranno a far parte di OpenBSD 7.5. Contestualmente, \u00e8 stata creata una versione stabile di LibreSSL 3.8.3, che corregge alcuni errori specifici per Windows e potenzia il supporto per il meccanismo di protezione CET (Control-flow Enforcement Technology).      <\/p>\n<p>Caratteristiche di LibreSSL 3.9.0:   <\/p>\n<ul>\n<li class=\"l\"> Aggiunto il supporto per algoritmi di firma digitale basati su ECDSA con hash SHA-3.\n<li class=\"l\"> Aggiunto il supporto HMAC con hash troncati SHA-2 e SHA-3 come PBE PRF.\n<li class=\"l\"> Sono state apportate modifiche per migliorare la portabilit\u00e0 su altre piattaforme. Per evitare problemi con il collegamento statico, la maggior parte dei simboli esportati di LibreSSL utilizzati per garantire la compatibilit\u00e0 \u00e8 preceduta dal prefisso \u00ablibressl_\u00bb. Nelle build basate su CMake \u00e8 stata interrotta l'esportazione dei simboli compat di libcrypto.\n<li class=\"l\"> Sono state apportate modifiche mirate a migliorare la compatibilit\u00e0 con OpenSSL. Ad esempio, sono stati aggiunti nomi alternativi ChaCha20 e chacha20 per l'algoritmo ChaCha, unificato il funzionamento delle funzioni SSL_library_init() e OPENSSL_init_ssl(), e resi conformi ai comportamenti di OpenSSL le chiamate a EVP_{CIPHER,MD}_CTX_init().\n<li class=\"l\"> Nell'utilit\u00e0 openssl \u00e8 stata aggiunta la supporto per i flag \u00ab-new -force_pubkey\u00bb, \u00ab-multivalue-rdn\u00bb, \u00ab-set_issuer\u00bb, \u00ab-set_subject\u00bb e \u00ab-utf8\u00bb.\n<li class=\"l\"> Effettuato il passaggio dall'uso della chiamata OBJ_bsearch_() alla funzione standard bsearch().\n<li class=\"l\"> Semplificata l'implementazione della funzione by_file_ctrl(), EVP_Cipher{Init,Update,Final}() e API OBJ_.\n<li class=\"l\"> \u00c8 stata effettuata una grande riorganizzazione dell'API EVP. Rimosse le funzioni EVP_add_{cipher,digest}().\n<li class=\"l\"> Semplificata la gestione di X509_TRUST.\n<li class=\"l\"> Riscritte le funzioni BIO_dump*().\n<li class=\"l\"> Cessato il supporto per le tabelle globali non adattate per l'uso multi-thread. Di conseguenza, non \u00e8 pi\u00f9 supportata l'assegnazione di nomi alternativi a cifrature e hash, l'aggiunta di stringhe personalizzate, metodi ASN.1, PKEY e CRL.\n<li class=\"l\"> Rimosse le funzioni BIO_set(), BIO_{sn,v,vsn}printf(), sk_find_ex() e OBJ_bsearch_(), cos\u00ec come un gran numero di funzioni obsolete dell'API CRYPTO.\n<li class=\"l\"> Interrotto l'accesso pubblico all'API X509_CERT_AUX e X509_TRUST.\n<li class=\"l\"> Il supporto per gli algoritmi GOST e STREEBOG \u00e8 stato interrotto.\n<li class=\"l\"> Espanso il supporto per il meccanismo CET (Control-flow Enforcement Technology), utilizzato per proteggere contro l'esecuzione di exploit basati su tecniche di programmazione orientata al ritorno (ROP, Return-Oriented Programming).     <\/ul>\n<p>Fonte: <a
