HMAC vs Other Authentication Methods: A Comparison - LinkedIn

In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. As with any MAC, it may be used to … See more 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 … See more The following pseudocode demonstrates how HMAC may be implemented. The block size is 512 bits (64 bytes) when using one of the … See more The cryptographic strength of the HMAC depends upon the size of the secret key that is used and the security of the underlying hash function used. It has been proven that the security of an HMAC construction is directly related to security properties of the … See more The design of the HMAC specification was motivated by the existence of attacks on more trivial mechanisms for combining a key with a hash function.
