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 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.
