title: How to download private key certificate Distribucion iOS?
body: <p>I appreciate if someone can guide me about the use of the iOS Distribution Certificates of the Apple development store.
  I see that there are already three iOS Distribution certificates created and that this is the limit, therefore I cannot create another one. I have an application that I will upload to the Apple store, but the following error message appears:</p>
  
  <p><strong>Missing private key for signing certificate. Failed to locate te private key  in the keychain</strong></p>
  
  <p>My question is, to get that private key, is it possible to download it from the developer store? or how can I get it?</p>
