How does a rainbow table help an attacker

WebMar 31, 2014 · An attack using this method is called a Rainbow Attack. There is however a simple way to make this type of attack infeasible: Salting your passwords. Salt for the Password Soup A Salt is a random string that is appended to the value we want to hash (the password) before the hash function is applied. The salt does not need to be secret. WebWithout using a salt, you can precompute a rainbow table for any password. A salt would make the attacker have to precompute a rainbow table for every different salt.
