Description-en: PAM module for password strength policy enforcement
passwdqc is a password/passphrase strength checking and policy
enforcement toolset, including a PAM module (libpam-passwdqc),
command-line programs (pwqcheck and pwqgen), and a library (libpasswdqc0).
.
pam_passwdqc (optionally) integrates with PAM such that it gets invoked
when users change their passwords. The module 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.
