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 (26 to 81).
- 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.
