- No.
- It should do this check then recrypt with a different salt.
- It should keep doing this until it runs out of salts or it
- manages not to get a match.
-
- If it can't find a valid salt it should issue a security alert
- and close all effected accounts, be carful not to close root's
- :-), as this password is comprimised. 4096 people have chosen it
- as there password so it must be guessable.
-
- ( You could apply the above with less clashes. If you get 05
- matches I would think the password chosen would be to guessable
- )

- Mark.
