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).
