// -*- coding: utf-8; tab-width: 2; indent-tabs-mode: nil; -*-
//
// Generates Wi-Fi passwords generated in the web interface of the “La box de
// SFR” home router.
//
// In many browsers, this implementation is broken because of a very short
// period of the pseudo-random Math.random() funciton, usually around 2^30.
//
// You can generate a passwords file of several gigabytes and run a
// successfull bruteforce attack in a couple of hours against A WPA key.
