WebNov 14, 2024 · A cryptographic salt is additional input other than message itself for a hash function so that it prevents attacker from launching dictionary attacks . Usually the salt is stored along with the hash of say the password etc. Keyed Hashing is secret key is used as input for hashing along with message like HMAC . Cryptographic salts are broadly used in many modern computer systems, from Unixsystem credentials to Internet security. Salts are closely related to the concept of a cryptographic nonce.
