10
12 pwscore is a simple tool for checking quality of a password. The
13 password is read from stdin.
14
15 The tool uses the libpwquality library to perform configurable checks
16 for minimum length, dictionary checking against cracklib dictionaries,
17 and other checks.
18
19 It either reports an error if the password fails any of the checks, or
20 it prints out the password quality score as an integer value between 0
21 and 100.
22
23 The password quality score is relative to the minlen setting in the
24 configuration file. But in general values below 50 can be treated as
25 moderate quality and above it fairly strong quality. Any password that
26 passes the quality checks (especially the mandatory cracklib check)
27 should withstand dictionary attacks and scores above 50 with the
28 default minlen setting even fast brute force attacks.
29
31 The first and only optional argument is the user name that is used to
32 check the similarity of the password to the username.
33
35 /etc/security/pwquality.conf - The configuration file for the
36 libpwquality library.
37
39 pwscore returns 0 on success, non zero on error.
