These functions allow you to use the CrackLib library to test the
'strength' of a password. The 'strength' of a password is tested by that
checks length, use of upper and lower case and checked against the
specified CrackLib dictionary. CrackLib will also give helpful diagnostic
messages that will help 'strengthen' the password.
