WebNov 6, 2024 · HMAC is a cryptographic method that guarantees the integrity of the message between two parties. HMAC algorithm consists of a secret key and a hash function. The secret key is a unique piece of information or a string of characters. It is known both by the sender and the receiver of the message. WebHMAC(key, msg, hash_func) -> hash. The results MAC code is a message hash mixed with a secret key. It has the cryptographic properties of hashes: irreversible, collision resistant, etc. The hash_func can be any cryptographic hash function like SHA-256, SHA-512, RIPEMD-160, SHA3-256 or BLAKE2s.
