title: How to find the value of the key?
body: <p>I have to find the key from this javascript.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>function generateKey() {
                  var i = 1;
                  var x = 64;
                  var n = 5493;
                  while (i &lt;= 25) {
                      x = (x * i) % n;
                      i++;
                  }
                  key = "flag_" + Math.abs(x);
              }
              
              generateKey();
              
              // Encode the message using the 'key'
              function encode() {                                                        
                  var input = $("#inputmessage").val();
                  var output = CryptoJS.AES.encrypt(input, key);
                  $("#outputmessage").val(output);
              }        </code></pre>
  </div>
  </div>
  
  I'm confused by what function generatekey does.  Also does anyone know what "flag_" means.  Any help in figuring this out is greatly appreciated.</p>
