PECL extension to cracklib
This package provides an interface to the cracklib libcrack libraries that come standard on most Unix-like distributions. This allows you to check passwords against dictionaries of words to ensure some minimal level of password security.

It tries to generate words from your username and gecos entry to tries to match them against what you’ve chosen.
It checks for simplistic patterns.
It then tries to reverse-engineer your password into a dictionary word, and searches for it in your dictionary.
after all that, it’s PROBABLY a safe-ish password. 8-
