== We're Using GitHub Under Protest ==
This project is currently hosted on GitHub. This is not ideal; GitHub is a proprietary, trade-secret system that is not Free and Open Souce Software (FOSS). We are deeply concerned about using a proprietary system like GitHub to develop our FOSS project. For further version of this projects, have a look My web bazzar where most of my ideas are still published until I made a choice for further shares...
We urge you to read about the Give up GitHub campaign from the Software Freedom Conservancy to understand some of the reasons why GitHub is not a good place to host FOSS projects.
If you are a contributor who personally has already quit using GitHub, please send mail to gitproj@f-hauri.ch for any comment or contributions without using GitHub directly.
Any use of this project's code by GitHub Copilot, past or present, is done without our permission. We do not consent to GitHub's use of this project's code in Copilot.

This pass phrase generator take clean words from dictionary to build random phrases and compute entropy.
Follow the idea found at: http://xkcd.com/936/
It is a perl script that take a dictionary file,
create a uniq cleaned words list (with only flat lower letters from a to z)
take randoms words and compute entropy.
Usage: passphrase.pl [-h] [-q] [-d dict file] [-s outputfile]
[-i mIn length] [-a mAx length] [-e entropy bits] [-r random file]
[-w words] [-l lines] [lines]
Version: passphrase.pl v1.5.1.2 - (2013-07-05 08:51:52).
-h This help.
-l num number of phrases to generate (default: 1)
-w num number of words by phrase (default: 5)
-e bits Entropy bits for each words (default: 15)
-d filename Dictionary file (default: /usr/share/dict/american-english)
-s filename Dict file to save after initial drop (default: none)
-i length Minimal word length (default: 4)
-a length Maximal word length (default: 11)
-r device Random file or generator (default: /dev/urandom)
-q Quietly generate lines without computations.
$ ./passphrase.pl -l 4 With 5 words over 32768 ( 15 entropy bits ) = 1/3.777893e+22 -> 75 bits. With 5 words from 56947 ( 15.797 entropy bits ) = 1/5.988999e+23 -> 78.987 bits. 3.634 192.718 airfoils desolated babysitting hits digresses 3.391 173.916 acidic parents scary trespassed fascinate 3.704 164.515 occluded rarely sweatier metallic squat 3.907 192.718 available stockpiling blazoning jaywalk chino
Explanation: There are 56947 word (15.79bits) containing 4 to 11 letters in /usr/share/dict/american-english, after randomly dropped this down to 32768 (round to 15 bits entropy), building lines of 5 random words, compute shannon's entropy and flat entropy, for each lines and printout.
