title: How to obtain Signing certificate fingerprint (SHA1) for OAuth 2.0 on Android?
body: <p>I'm trying to register my android app following the steps in  <a href="https://developers.google.com/console/help/#installed_applications" rel="noreferrer">https://developers.google.com/console/help/#installed_applications</a> which leads me to follow 
  <a href="http://developer.android.com/tools/publishing/app-signing.html" rel="noreferrer">http://developer.android.com/tools/publishing/app-signing.html</a>.</p>
  
  <p>However, I'm not sure how to get the signing certificate fingerprint (SHA1). </p>
  
  <p>I first used the Eclipse ADT plugin to export and create the keystore/key.
  Then, I tried doing <code>keytool -list keystore mykeystore.keystore</code> and it gives me a MD5 Certificate fingerprint.  Do I need to redo the signing (meaning I can't use the eclipse export wizard)? </p>
  
  <p>Can I use a debug certificate first?</p>
