title: How to decrypt express-session cookie value in browser?
body: <p><a href="https://www.npmjs.com/package/express-session" rel="nofollow noreferrer">https://www.npmjs.com/package/express-session</a></p>
  <p>I saved my session information in cookies through a module called express-session.<br />
  Of course, this was hashed through the secretkey I supplied.<br />
  However, for debugging purposes, I want to check this value in the browser.</p>
  <p>This is what i can see in my browser
  <code>s%3AdiNiZbm2WZvcmn6sJtl1VPvdrRIv9Yvw.M0mQUA9J3dEKybewFq5rTMJWg7dcazbZ6YvKRH9Nxo0</code></p>
  <p>I guess this value is hashed with <code>sha1</code>.
  But i don't know how to read it....</p>
  <p><em>It would be great if express-session had an option to send without hashes. there was no such option</em></p>
  <p>If i can decipher it, I guess it would be something like this.</p>
  <pre><code>cryptojs.decrypt.sha1(cyper,mykey)
  </code></pre>
