title: Unknown encoding similar to base64
body: <p>I have looked at a variety of questions regarding strings with an encoding similar to base64, but none of them helped me with this string:</p>
  
  <pre><code>khvVM0gpOpAP/mUxEa90mrkiNGJ1vBPgygZJMuMrNcY=
  </code></pre>
  
  <p>It is from an HTTP request. The header name is <code>X-Request-Token</code>. Any ideas?</p>
