WebMar 24, 2024 · If you are using random numbers and letters (upper and lower case) for salts, you can make the assumption that each character has 5.9 bits of entropy, assuming they are actually random. A salt needs to be unique enough never to be used by 2 users that happen to have the same password. WebA salt is a unique, randomly generated string that is added to each password as part of the hashing process. As the salt is unique for every user, an attacker has to crack hashes one at a time using the respective salt rather than calculating a hash once and comparing it against every stored hash.
