A password/passphrase strength checking and policy enforcement toolset
passwdqc is a password/passphrase strength checking and policy enforcement toolset, including a PAM module (pam_passwdqc), command-line programs (pwqcheck, pwqfilter, and pwqgen), and a library (libpasswdqc). pam_passwdqc is normally invoked on password changes by programs such as passwd(1). It is capable of checking password or passphrase strength, enforcing a policy, and offering randomly-generated passphrases, with all of these features being optional and easily (re-)configurable. pwqcheck and pwqgen are standalone password/passphrase strength checking and random passphrase generator programs, respectively, which are usable from scripts. The pwqfilter program searches, creates, or updates binary passphrase filter files, which can also be used with pwqcheck and pam_passwdqc. libpasswdqc is the underlying library, which may also be used from third-party programs.
