Projekt LibreSSL orijentiran je na kvalitetnu podr\u0161ku SSL\/TLS protokola uz uklanjanje suvi\u0161nih funkcionalnosti, dodavanje dodatnih sigurnosnih sredstava i zna\u010dajno \u010di\u0161\u0107enje i preure\u0111ivanje koda. Izdanje LibreSSL 3.9.0 smatra se eksperimentalnim, u kojem se razvijaju mogu\u0107nosti koje \u0107e u\u0107i u sastav OpenBSD 7.5. Istovremeno, formirano je stabilno izdanje LibreSSL 3.8.3, u kojem su ispravljene neke specifi\u010dne gre\u0161ke za Windows i poja\u010dana podr\u0161ka za mehanizam za\u0161tite CET (Control-flow Enforcement Technology).      <\/p>\n<p>Zna\u010dajke LibreSSL 3.9.0:   <\/p>\n<ul>\n<li class=\"l\"> Dodana je podr\u0161ka za algoritme digitalnog potpisa temeljene na ECDSA s SHA-3 hashovima.\n<li class=\"l\"> Dodana je podr\u0161ka za HMAC s skra\u0107enim SHA-2 i SHA-3 hashovima kao PBE PRF.\n<li class=\"l\"> Unesene su izmjene za pobolj\u0161anje prenosivosti na druge platforme. Kako bi se izbjegli problemi pri stati\u010dkom povezivanju, ve\u0107ina kori\u0161tenih simbola LibreSSL za osiguravanje kompatibilnosti sada ima prefiks 'libressl_'. U CMake baziranim gradnjama prestao je izvoz compat simbola libcrypto.\n<li class=\"l\"> Unesene su izmjene usmjerene na pobolj\u0161anje kompatibilnosti s OpenSSL-om. Na primjer, dodani su nadimci ChaCha20 i chacha20 za algoritam ChaCha, ujedna\u010den je rad funkcija SSL_library_init() i OPENSSL_init_ssl(), a pozivi EVP_{CIPHER,MD}_CTX_init() dovedeni su u skladu s pona\u0161anjem OpenSSL-a.\n<li class=\"l\"> Alatu openssl dodana je podr\u0161ka za zastavice '-new -force_pubkey', '-multivalue-rdn', '-set_issuer', '-set_subject' i '-utf8'.\n<li class=\"l\"> Pre\u0161ao se s kori\u0161tenja poziva OBJ_bsearch_() na standardnu funkciju bsearch().\n<li class=\"l\"> Pojednostavljena je implementacija funkcije by_file_ctrl(), EVP_Cipher{Init,Update,Final}() i API OBJ_.\n<li class=\"l\"> Provedena je velika reorganizacija API EVP. Uklonjene su funkcije EVP_add_{cipher,digest}().\n<li class=\"l\"> Pojednostavljena je obrada X509_TRUST.\n<li class=\"l\"> Prepisane su funkcije BIO_dump*().\n<li class=\"l\"> Prekinuta je podr\u0161ka za globalne tablice koje nisu prilago\u0111ene za vi\u0161edretveno kori\u0161tenje. U vezi s tim sada nije podr\u017eano dodjeljivanje nadimaka \u0161iframa i hashovima, dodavanje vlastitih nizova, ASN.1 metoda, PKEY i CRL.\n<li class=\"l\"> Uklonjene su funkcije BIO_set(), BIO_{sn,v,vsn}printf(), sk_find_ex() i OBJ_bsearch_(), kao i mnoge zastarjele funkcije API CRYPTO.\n<li class=\"l\"> Prekinut je javni pristup API X509_CERT_AUX i X509_TRUST.\n<li class=\"l\"> Prekinuta je podr\u0161ka za algoritme GOST i STREEBOG.\n<li class=\"l\"> Pro\u0161irena podr\u0161ka za CET (Control-flow Enforcement Technology) mehanizam, koji se koristi za za\u0161titu od
