title: Get client UUID from browser
body: <p>I want to get client UUID (the user's computer UUID), when user accesses my website. Actually, I will be encrypting something a user can download and it will open in my application only. In my application I am getting UUID on the run and decrypting using this:</p>
  <pre><code>os.popen('wmic csproduct get UUID').read()
  </code></pre>
  <p>Everything its working fine, now the only limitation is that I couldn't find any way to get UUID of the client from my website, so that I can encrypt along with some other hashes that my application know and can add as salt and decrypt. My website id developed on Django.</p>
  <p><strong>Note</strong></p>
  <ul>
  <li>User is going to download my application that will be in form of .exe file, can I use some script inside my application to send UUID to my website ?</li>
  <li>I think I need to write some script that user will download and it will send me the data all the time and then I will allow the user to download, anyone can guide me on this ?</li>
  <li>I know you can ask what if user changes the system etc. I just want to get UUID for now I have taken care of other things already.</li>
  <li>For now lets say I want to work on windows only, no Linux or Mac user</li>
  </ul>
  <p><strong>Edit</strong></p>
  <p>Some folks are getting confused by UUID I mean the &quot;Universal Unique Identifier&quot; of the computer on which a person is accessing my website.</p>
