gpw - program to generate pronounceable passwords
gpw [number_of_passwords [length_of_passwords]]
This manual page documents briefly the gpw command. This manual page
was written for the Debian GNU/Linux distribution because the original
program does not have a manual page.
Gpw is a program that generate pronounceable passwords of whatever
length is desidered. It uses the statistics of three-letter
combinations (trigraphs) of the english system dictionary. It is based
on the ideas in Morrie Gasser’s password generator for Multics, and Dan
Edwards’s generator for CTSS. FIPS Standard 181 describes a similar
digraph-based generator, derived from Gasser’s.
This program accepts two optional numbers as command-line arguments.
The first value is the number of password to generate, the second one
is the length of the passwords required, up to 99. Defaults are 10 and
Password length should be choosen consistently with the encryption
So, a value of eight is useful with DES encryption, and a longer value
should be used with MD5 encryption.
