Web21. The usual answer is that a salt can be make public; if that was a problem, then the salt would not be called a "salt" but a "key". In some protocols, unauthenticated obtention of the salt is the norm, and is not considered to be a problem. E.g. with SRP, a password-authenticated key exchange, where any salting and hashing must necessarily ... 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 .

Salt and Password can be stored together because every random salt is different and that makes attacker to brute force each password. So rainbow table also need to be created again for each salt. Same password need to be brute forced each time as well. daniel ofer and lina ofer
