WebJun 6, 2024 · The use of either a hash-based MAC ( HMAC) or block-cipher-based MAC is recommended as long as all underlying hash or symmetric encryption algorithms are also recommended for use; currently this includes the HMAC-SHA2 functions (HMAC-SHA256, HMAC-SHA384 and HMAC-SHA512). WebFeb 25, 2024 · Recap. A cryptographic salt is made up of random bits added to each password instance before its hashing. Salts create unique passwords even in the instance of two users choosing the same passwords. Salts help us mitigate hash table attacks by forcing attackers to re-compute them using the salts for each user.
