NAME¶
pwqgen
—
Generate quality controllable random passphrase
SYNOPSIS¶
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.
