For those of you not familiar with the CrackLib Library:
CrackLib (or PHP Crack) can not cope with plaintext wordlists.
You have to generate a binary version of any plaintext list first.
After you have done this you get 3 files with different extensions:
crack_opendict() must be called with the first argument describing the path and base filename of the binary wordlist, e.g. C:\....\my_list or /usr/local/... (see below)
Now the bad news - how to generate the 3 files:
The only way i managed to do it:
o Download the CrackLib package from sourceforge (see link in php.net txt)
o USE UNIX/LINUX:
o run configure
o run make all
o run make install
o run make dict (having the wordlists in the /dict directory)
o look for the files in /usr/local/share/cracklib/
o copy the files in a convenient directory
XIV. Crack Functions
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.
Huomaa: This extension has been moved to the PECL repository and is no longer bundled with PHP as of PHP 5.0.0.
More information regarding CrackLib along with the library can be found at http://www.crypticide.com/users/alecm/.
This PECL extension is not bundled with PHP. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: http://pecl.php.net/package/crack.
In PHP 4 this PECL extensions source can be found in the ext/ directory within the PHP source or at the PECL link above. In order to use these functions you must compile PHP with Crack support by using the --with-crack[=DIR] configuration option.
Windows users will enable php_crack.dll inside of php.ini in order to use these functions. In PHP 4 this DLL resides in the extensions/ directory within the PHP Windows binaries download. You may download this PECL extension DLL from the PHP Downloads page or at http://snaps.php.net/.
The behaviour of these functions is affected by settings in php.ini.

This example shows how to open a CrackLib dictionary, test a given password, retrieve any diagnostic messages, and close the dictionary.
