Denne udgivelse inkluderer flere API-\u00e6ndringer, hvoraf nogle er ganske betydelige, samt fjernelse af for\u00e6ldede funktioner. En bem\u00e6rkelsesv\u00e6rdig ny funktion er underst\u00f8ttelsen af SLH-DSA signaturer (en digital signaturalgoritme baseret p\u00e5 tilstandsl\u00f8s hashing).<br \/>Dette er en ny stor udgivelse. Den inkluderer underst\u00f8ttelse af SLH-DSA. Der er foretaget flere \u00e6ndringer i Nettle API'et, og for\u00e6ldede funktioner er blevet fjernet. Derudover er ABI'en forbedret, hvilket har resulteret i, at API'et stort set er forblevet u\u00e6ndret, is\u00e6r er kontekststrukturerne for flere algoritmer blevet reduceret...<\/p>\n<\/blockquote>\n<p><b>\u00c6ndringer:<\/b><\/p>\n<ul>\n<li> I _digest -funktionerne i hashing-algoritmer, MAC og AEAD tager man ikke l\u00e6ngere \u00f8nsket st\u00f8rrelse p\u00e5 digests som argument; de returnerer i stedet altid digests af fuld st\u00f8rrelse. Derfor er typen nettle_hash_digest_func ogs\u00e5 blevet \u00e6ndret.<\/li>\n<li> Funktioner til behandling af fulde meddelelser ved hj\u00e6lp af CCM AES accepterer nu en konstant krypteringskontekst som det f\u00f8rste argument. For eksempel er det f\u00f8rste argument til funktionen ccm_aes128_encrypt_message nu en konstant struktur aes128_ctx*. Tidligere var det en struktur ccm_aes128_ctx*, der ignorerede alt bortset fra den grundl\u00e6ggende krypteringskontekst.<\/li>\n<li> Nu bruger SHA3-funktionerne den samme struktur sha3_ctx for alle hash-varianter samt den samme funktion sha3_init. De gamle navne, s\u00e5som sha3_256_ctx og sha3_256_init, er defineret som pr\u00e6processor-aliasser for at sikre bagudkompatibilitet.<\/li>\n<li> Argumentet dst_length for funktionerne base16_decode_update og base64_decode_update er nu b\u00e5de et indgangs- og udgangsargument. Det skal indeholde st\u00f8rrelsen p\u00e5 target-bufferet, dekodningen vil mislykkes, hvis denne st\u00f8rrelse ikke er tilstr\u00e6kkelig. Tidligere var dst_length kun et udgangsargument, og det var n\u00f8dvendigt, at target-bufferet var stort nok til enhver indgangsv\u00e6rdi med en given l\u00e6ngde src_length.<\/li>\n<\/ul>\n<p>Kilde: <a \ncontent=\"nofollow\" rel=\"nofollow\"
