Webb17 dec. 2015 · Hash-Based Message Authentication Codes (HMACs) are a group of algorithms that provide a way of signing messages by means of a shared key. In the case of HMACs, a cryptographic hash function is used (for instance SHA256). The strength (i.e. how hard it is to forge an HMAC) depends on the hashing algorithm being used. WebbThe Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". tremor the series
