WebbIf a user has a very simple password such as “passw0rd”, a random salt is attached to it prior to hashing, say “{%nC]&pJ^U:{G#*zX<;yHwQ”. With a simple hash, an attacker just has to generate one huge dictionary to crack every user’s password. If salted, the attacker has to regenerate the least for each user (using the salt for each user).
