title: Unable to export Apple production push SSL certificate in .p12 format
body: <p>I am using Urban airship in my application for push notification. So, I need to download the push SSL certificate from Apple developer portal. After downloading, I added that in keychain access. But no private key was created for the certificate. When I tried to right click and export the certificate, I was not able to export that as <em>.p12</em> file as the <em>.p12</em> file extension was disabled while saving. I am unable to attach the screenshots here due to lesser reputation.</p>
  
  <p>Someone please tell me where is the issue here. How should I do that?</p>
