gpw (1)

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 8 respectively.

Password length should be choosen consistently with the encryption standard used.

So, a value of eight is useful with DES encryption, and a longer value should be used with MD5 encryption.
