Crypt::PassGen

--------------

This module provides a single command for generating random password

that is close enough to a real word that it is easy to remember.

It does this by using the frequency of letter combinations in 

a language (the frequency table is generated during installation

although multiple tables can be generated and used for different

languages).

This module should not be used for high security applications

(such as user accounts) since it returns passwords that are not

mixed case, have no punctuation and no letters. This word can be

used as a basis for a more secure password.

The language of the password depends on the language used to construct

the frequency table.

The source repository is on github: https://github.com/timj/perl-Crypt-PassGen

Requirements

------------

Currently assumes /usr/dict/words or /usr/share/dict/words is available so that the

frequency table can be constructed. On non-unix systems it might

be easier simply to include a dictionary for this within the

distribution. 

Also requires the Storable module.

Installation

------------

  perl Makefile.PL

  make

  make test

  make install

The first step may take a well since a freqeuncy table is generated

as part of the installation. If /usr/dict/words is not available

the location of a suitable dictionary must be put into the

Makefile.PL

Derivation

----------

This algorithm is based on that used in the PASSGEN program written by

Mike Bartman of SAR, Inc as part of the SPAN security toolkit in 1989.

Status

------

This is an early release of this module. It has not been tested

extensively and must be considered in alpha release.

Release Notes

-------------

V0.06   - Ensure that passwords are always the right length. In rare

          cases the loop would exit early and return a shorter password.

          Thanks to Vadim Pushtaev for the fix.

V0.05   - Fix typo in call to _scale_thirds_down preventing the

          module from working in some situations. Fix typo in call

          to _scale_seconds_down during database build
