// 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. | |
// | |
// This snippet was successfully tested using Node.js against a password | |
// generated in Google Chrome. | |
// | |
// Please note, this snippet was quickly designed as a proof and has some | |
// flaws. You will need to run it at least twice to initialize it with | |
// different seeds that will result in disjoint password files. And the | |
// output becomes periodic sooner than estimated, you might not need to run | |
// it to the very end. | |
// | |
// Usage: | |
// $ node gen_wifi_pwd_sfr_box.js > passwords | |
