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, … WebMay 12, 2015 · No, message commitment by disclosing its HMAC-MD5 with a key later revealed is no longer any secure, because of the ease with which MD5 collisions can now be found.There's however no compelling evidence that's insecure for messages constrained to belong in a small arbitrary set that no adversary can choose or influence.Still, …
