NAME

       pwscore - simple configurable tool for checking quality of a password

SYNOPSIS

       pwscore [user]

DESCRIPTION

       pwscore is a simple tool for checking quality of a password. The password is read from stdin.

       The tool uses the libpwquality library to perform configurable checks for minimum length, dictionary
       checking against cracklib dictionaries, and other checks.

       It either reports an error if the password fails any of the checks, or it prints out the password quality
       score as an integer value between 0 and 100.

       The password quality score is relative to the minlen setting in the configuration file. But in general
       values below 50 can be treated as moderate quality and above it fairly strong quality. Any password that
       passes the quality checks (especially the mandatory cracklib check) should withstand dictionary attacks
       and scores above 50 with the default minlen setting even fast brute force attacks.

OPTIONS

       The first and only optional argument is the user name that is used to check the similarity of the
       password to the username.

FILES

       /etc/security/pwquality.conf - The configuration file for the libpwquality library.

RETURN CODES

       pwscore returns 0 on success, non zero on error.
