All Applications Included on the DVD  cracklib 2.8.9-3.3: A
password-checking library. 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 performs several tests on passwords:
it tries to generate words from a username and gecos entry and
checks those words against the 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 package.   YDL.net Fixstars
