Password strength checking with passwdqc

passwdqc is a simple password strength checking module for PAM-aware password changing programs, such as passwd(1). In addition to checking regular passwords, it offers support for passphrases and can provide randomly generated ones. All features are optional and can be (re-)configured without rebuilding.

The passwdqc 1.1.0+ package additionally includes libpasswdqc (a password/passphrase strength checking library), pwqcheck (a standalone password/passphrase strength checking program), and pwqgen (a standalone random passphrase generator program).

Changes in version 1.1.3:

• An “official” and documented way to build and install all components but the PAM module on systems without PAM has been introduced.
• The “personal login information” check has been enhanced to consider the user’s home directory path and name (in addition to the username and full name).
• The code has been made more portable.
