Re: What's the idea of different salts in crypt()?by wog (Curate) |

The reason that salts are used is to make it
harder to break a crypted password file.
Instead of being able
to go through a dictionary or similar and compare
the crypted value of every word to every password,
they can only work on passwords with one salt.
This makes the task of looking for an easily guessed
("insecure")
password within a password file much slower.
