NAME¶
pwqgen —
Generate quality controllable random passphrase
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 85).
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).
AUTHORS¶
The pam_passwdqc module was written for Openwall GNU/*/Linux by Solar Designer.
The pwqgen program was originally written for ALT
GNU/*/Linux by Dmitry V. Levin, indirectly reusing code from pam_passwdqc (via
libpasswdqc). This manual page was written for Openwall GNU/*/Linux by Dmitry
