URL : http://sourceforge.net/projects/cracklib/
License : LGPLv2+
Description : CrackLib tests passwords to determine whether they match certain
: security-oriented characteristics, with the purpose of stopping
: users from choosing passwords that are easy to guess. CrackLib

: password; it checks for simplistic patterns in passwords; and it
: checks for the password in a dictionary.
:
: CrackLib is actually a library containing a particular C function
: which is used to check the password, as well as other C
: functions. CrackLib is not a replacement for a passwd program; it
: must be used in conjunction with an existing passwd program.
:
: Install the cracklib package if you need a program to check users'
: passwords to see if they are at least minimally secure. If you
: install CrackLib, you will also want to install the cracklib-dicts
