title: How does Ionic/Cordova generate hash key?
body: <p>I'm working on adding Facebook API integration with ionic/Cordova and am trying to find the debug hash key that is generated for my app when I do:</p>
  
  <pre><code>ionic build android
  </code></pre>
  
  <p>I know that it generates a new .keystore file at /userhomedir/.android/debug.keystore. But <strong>what does it set as the alias and password</strong>? And how can I retrieve this hash key after Cordova has created it for my app. I don't see the hash key being printed anywhere during the build process.</p>
  
  <p>I need the generated hash key to give to Facebook API to use their sign on SDK</p>
