Como funcionam o algoritmos de hash da família SHA? Por exemplo o SHA-256 processa, assim como no SHA-1, mensagens de valor máximo equivalente a 264 bits e também faz uso de palavras com 32 bits A construção dos algoritmos de SHA-2 é muito semelhante à construção do algoritmo de SHA-1
What is the difference between SHA-3 and SHA-256? I am new about cryptography, I learned that SHA-3 (Secure Hash Algorithm 3) is the latest member of the Secure Hash Algorithm family of standards, released by NIST But I recently saw SHA-256 but
sha 256 - Does the signature length of RS256 depend on the size of the . . . SHA-256 is a 256-BIT hash = 32 bytes not 256 bytes Most cryptographic data is described in bits not bytes, although PKCS1 (nd JOSE) only supports multiples of a byte (formally octet) of 8 bits To be secure RSA modulus must be much bigger than is needed for the hash -- SHA-256 gives 128-bit strength but RSA-3072 is needed to match it (and some people do 4096 because it looks nicer) See
