Este lan\u00e7amento inclui v\u00e1rias altera\u00e7\u00f5es na API, algumas das quais s\u00e3o bastante significativas, al\u00e9m da remo\u00e7\u00e3o de fun\u00e7\u00f5es obsoletas. H\u00e1 uma nova funcionalidade not\u00e1vel: suporte a assinaturas SLH-DSA (algoritmo de assinatura digital baseado em hash sem estado).<br \/>Este \u00e9 um grande novo lan\u00e7amento. Ele inclui suporte ao SLH-DSA. V\u00e1rias altera\u00e7\u00f5es foram feitas na API Nettle, al\u00e9m da remo\u00e7\u00e3o de fun\u00e7\u00f5es obsoletas. Al\u00e9m disso, o ABI foi melhorado, resultando em uma API que permaneceu praticamente inalterada, em particular, as estruturas de contexto para v\u00e1rios algoritmos foram reduzidas\u2026<\/p>\n<\/blockquote>\n<p><b>Mudan\u00e7as:<\/b><\/p>\n<ul>\n<li> As fun\u00e7\u00f5es _digest dos algoritmos de hash, MAC e AEAD n\u00e3o aceitam mais o tamanho desejado do digest como argumento; em vez disso, elas sempre retornam um digest do tamanho completo. Assim, o tipo nettle_hash_digest_func tamb\u00e9m foi alterado.<\/li>\n<li> As fun\u00e7\u00f5es para processar mensagens completas usando CCM AES agora aceitam como primeiro argumento um contexto de criptografia constante. Por exemplo, o primeiro argumento da fun\u00e7\u00e3o ccm_aes128_encrypt_message agora \u00e9 uma estrutura constante aes128_ctx*. Antes, era uma estrutura ccm_aes128_ctx*, que ignorava tudo, exceto o contexto b\u00e1sico de criptografia.<\/li>\n<li> Agora as fun\u00e7\u00f5es SHA3 usam a mesma estrutura sha3_ctx para todas as variantes de hash, bem como a mesma fun\u00e7\u00e3o sha3_init. Nomes antigos, como sha3_256_ctx e sha3_256_init, foram definidos como apelidos do pr\u00e9-processador para garantir a compatibilidade retroativa.<\/li>\n<li> O argumento dst_length das fun\u00e7\u00f5es base16_decode_update e base64_decode_update agora \u00e9 um argumento de entrada e sa\u00edda ao mesmo tempo. Na entrada, ele deve conter o tamanho do buffer de destino; a decodifica\u00e7\u00e3o falhar\u00e1 se esse tamanho for insuficiente. Antes, dst_length era apenas um argumento de sa\u00edda, e era necess\u00e1rio garantir que o buffer de destino fosse grande o suficiente para qualquer valor de entrada de comprimento src_length especificado.<\/li>\n<\/ul>\n<p>Fonte: <a \ncontent=\"nofollow\" rel=\"nofollow\"
