What is `cracklib.x86_64`

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 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.
