Uses the OpenBSD build system and can be installed by

NAME

rndpasswd - create random passwords

SYNOPSIS

rndpasswd [-aenrs] [-b rounds] [-l length]

DESCRIPTION

rndpasswd prints random strings to standard output. The default output is of length 12 and consists of alphanumeric and special characters.

The options are as follows:

-a

Use alphabet characters.

-b rounds

Rounds for bcrypt hashing (min: 4, max: 31, defaults to auto). This inferres -e.

-e

Output the encrypted password hash next to the string.

-l length

Length of output (min: 1, max: 127).

-n

Use numbers.

-r

Repeatedly print new random strings. One per line.

-s

Use special characters.

EXAMPLES

Generate new htpasswd entry:

$ PLAIN=$(rndpasswd); echo username:$PLAIN | htpasswd

Create a list of 20 plaintext and encrypted passwords using only numbers:

$ rndpasswd -enr | head -n 20

SEE ALSO

encrypt(1), htpasswd(1), arc4random(3), crypt_newhash(3)

CAVEATS

The result is truely random, there is no metric that guarantees that alphabetic cahracter and/or numbers and/or special charaters are present in the generated string.

You can’t perform that action at this time.
