Restricted Password List Generator

gistfile1.md

Basically, you forgot the password (for something, e.g. keystore) and need to generate a list of possible passwords to restrict the brute force possibilities.

For example you think it could be password, android or welcome, but could also be P@ssw0rd, aNdRoId! or Welcome1!.

Just modify the base_words (line 4) and suffixes (line 5) and run the script (you need node). It will output each possibility to the console. Or pipe it to a file.

./word_generator > words.txt

word_generator

#!/usr/bin/env node

//example world list
var base_words= ["password", "android", "welcome"];
var suffixes = ["", "1", "!", "1!"];


function buildWords(letters) {
  if (letters.length === 0) {
    return suffixes;
  }
  var first = letters[0];
  var rest = buildWords(letters.slice(1));
  return first.reduce(function(acc, letter) {
    return acc.concat(rest.map(function(r) { return letter + r;}));
  }, []);

}

function getLetters(word) {
  var letters = word.split("").map(function(l) {
    var ret = [];
    l = l.toLowerCase();
    ret.push(l);
    ret.push(l.toUpperCase());

    if (l === "e") {
      ret.push("3");
    } else if (l === "a") {
      ret.push("@");
    } else if (l === "i") {
      ret.push("!");
      ret.push("1");
    } else if (l === "s") {
      ret.push("5");
      ret.push("$");
    } else if (l === "o") {
      ret.push("0");
    }

    return ret;
  });
  return letters;
}

function buildWordList(word) {
  return buildWords(getLetters(word));
}

base_words.forEach(function(word) {
  var word_list = buildWordList(word);
  var length = word_list.length;
  word_list.forEach(function(o, idx) {
    console.log(o);
  });
});
