Block diagram of hash function
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, … WebFeb 26, 2024 · The below block diagram shows how we can achieve this to store passwords securely, in our application! Hash Function. Notice that the hash function ensures that the length of the hashed output remains the same, and much larger than the length of the input string. So, this makes it very difficult to crack such hashes using brute …
