Cryptanalysis on hmac/nmac-md5 and md5-mac

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, … WebCryptanalysis refers to the study of ciphers, ciphertext , or cryptosystems (that is, to secret code systems) with a view to finding weaknesses in them that will permit retrieval of the …
