NAME

pwqgen — Generate quality controllable random passphrase

SYNOPSIS

pwqgen [options]

DESCRIPTION

The pwqgen program generates a random passphrase using the libpasswdqc library. Strength of the generated passphrase depends on the amount of randomness read from /dev/urandom.

OPTIONS
random=N

(default: random=47) The size of randomly-generated passphrase in bits (24 to 136).

config=FILE

Load config FILE in the passwdqc.conf format. This file may define any options described in passwdqc.conf(5), but only the random and config options are honored by pwqgen.

--version

Output pwqgen program version and exit.

-h, --help

Output pwqgen help text and exit.

EXIT STATUS

pwqgen exits with non-zero status when it encounters invalid config file, invalid option, invalid parameter value, when it fails to obtain enough randomness, and in any case when it fails to generate a passphrase.

FILES

/etc/passwdqc.conf (not read unless this suggested file location is specified with the config=/etc/passwdqc.conf option).
