title: How to decrypt this strange Base64 hash?
body: <p>I was trying to decrypt this hash but with no success. The hash is <strong>Y_ZUP7l05osR3kg7T5jTYORC7CNeWA--</strong> and it's BASE64</p>
  
  <ul>
  <li>'=' is replaced with '-'</li>
  <li>'+' is replaced with '.'</li>
  <li>'/' is replaced with '_'</li>
  </ul>
  
  <p>So it's actually <em>Y/ZUP7l05osR3kg7T5jTYORC7CNeWA==</em> It prints out something strange <strong>cöT?¹tæÞH;OÓ`äBì#^X</strong> but the length of the strange output string coincide with the length of the input string.</p>
