title: Register Apple Service using a .pem certificate
body: <p>I would like to send a test PUSH message to an iOS device. I am provided with the device token and one <code>.pem</code> file as certificate. But I cannot seem to find a way to create a new <code>ApplePushChannelSettings</code> object using this <code>.pem</code> file. The examples on the web all use a <code>.p12</code> file that come with a password.</p>
  
  <pre><code>//Create our push services broker
  var push = new PushBroker();
  
  //Registering the Apple Service and sending an iOS Notification
  var appleCert = File.ReadAllBytes("ApnsSandboxCert.p12"));
  push.RegisterAppleService(new ApplePushChannelSettings(appleCert, "pwd"));
  push.QueueNotification(new AppleNotification()
                             .ForDeviceToken("DEVICE TOKEN HERE")
                             .WithAlert("Hello World!")
                             .WithBadge(7)
                             .WithSound("sound.caf"));
  </code></pre>
  
  <p>Should I ask for a <code>.p12</code> certificate for the target app or is there a way to use a <code>.pem</code> file with <em>PushSharp</em>?</p>
