pam_passwdqc: new recipe
pam_passwdqc is a simple password strength checking module for PAM-aware password changing 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.
