WebDetails. Any cryptographic hash function, such as SHA-2 or SHA-3, may be used in the calculation of an HMAC; the resulting MAC algorithm is termed HMAC-X, where X is the hash function used (e.g. HMAC-SHA256 or HMAC-SHA3-512).The cryptographic strength of the HMAC depends upon the cryptographic strength of the underlying hash function, … WebSkein is a cryptographic hash function and one of five finalists in the NIST hash function competition.Entered as a candidate to become the SHA-3 standard, the successor of SHA-1 and SHA-2, it ultimately lost to NIST hash candidate Keccak.. The name Skein refers to how the Skein function intertwines the input, similar to a skein of yarn.

WebJan 25, 2024 · A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The resulting output, which is known as a hash digest , hash value , or hash code, is the resulting unique identifier we mentioned earlier .

WebNov 5, 2024 · The hash output length does not need to be larger than 512 bits; the ECDSA specification can handle any length. The curve secp521r1 is usually considered to provide 256 bits of security (even though it provides a bit more), see Table 2 of NIST SP 800-57 for example.
