title: Using an Identity Server signing certificate in Azure
body: <p>In the IdentityServer sample code (startup.cs), we can see how to use a certificate:</p>
  
  <pre><code>var certFile = env.ApplicationBasePath + "\\idsrv3test.pfx";
  
  var signingCertificate = new X509Certificate2(certFile, "idsrv3test");
  </code></pre>
  
  <p>How do I do this in a production environment, if I am deploying my STS to Azure as a Web App Service?</p>
  
  <p>For security, I know I cannot add the pfx file to the solution.</p>
