title: Install local timestamp server for ClickOnce signing
body: <p>In our company we use signed ClickOnce applications that we develop ourselves. On the Signing page, there is an option to define a timestamp server, and it works when we use a URL from the internet like "<a href="http://timestamp.digicert.com" rel="nofollow noreferrer">http://timestamp.digicert.com</a>".</p>
  
  <p>But some of our pcs do not have internet access, so I want to try to use a timestamp server on our own network instead.
  How do I install such a server? 
  I have been unable to find this information anywhere, including in the documentation:</p>
  
  <p><a href="https://docs.microsoft.com/en-us/visualstudio/ide/how-to-sign-application-and-deployment-manifests?view=vs-2017" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/visualstudio/ide/how-to-sign-application-and-deployment-manifests?view=vs-2017</a></p>
  
  <p>I found this tool under OpenSSL:
  <a href="https://www.openssl.org/docs/manmaster/man1/ts.html" rel="nofollow noreferrer">https://www.openssl.org/docs/manmaster/man1/ts.html</a></p>
  
  <p>However, the page says; "There is no support for sending the requests/responses automatically over HTTP or TCP yet as suggested in RFC 3161. The users must send the requests either by ftp or e-mail."</p>
  
  <p>I think I will need HTTP for it to work.</p>
  
  <p>I also found these commercial products:</p>
