The attacker can better predict the password that legitimately maps to that hash. Hashed passwords are not unique to themselves due to the deterministic nature of hash function: when given the same input, the same output is always produced. A system like that in place will allow hackers to crack passwords in record time! Note: Never tell anyone using your registration forms that their selected password is not unique. If the attacker is hitting an online service with a credential stuffing attack, a subset of the brute force attack category, salts won't help at all because the legitimate server is doing the salting+hashing for you. However, there are limitations in the protections that a salt can provide. Consequently, the unique hash produced by adding the salt can protect us against different attack vectors, such as hash table attacks, while slowing down dictionary and brute-force offline attacks. The copy-paste of the page 'Hash Function' or any of its results, is allowed as long as you cite dCode!Ĭite as source (bibliography): Hash Function on dCode.Salting hashes sounds like one of the steps of a hash browns recipe, but in cryptography, the expression refers to adding random data to the input of a hash function to guarantee a unique output, the hash, even when the inputs are the same.
