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.
More information regarding CrackLib along with the library can be found at http://www.users.dircon.co.uk/~crypto/.
In order to use these functions, you must compile PHP with Crack support by using the --with-crack[=DIR] option.
