title: Google API access using Service Account oauth2client.client.CryptoUnavailableError: No crypto library available
body: <p>I am trying to create a service account app so that I can access Google Analytics api using Python.
  Two things are confusing me. First, when I use the following code:<br></p>
  
  <pre><code>`from oauth2client.client import SignedJwtAssertionCredentials
  client_email = "#####client_email#######.gserviceaccount.com"
  with open("XXXXXX.p12") as f:
     private_key = f.read()
  credentials = SignedJwtAssertionCredentials(client_email, private_key,'https://www.googleapis.com/auth/sqlservice.admin')`
  </code></pre>
  
  <p>I get the following error: </p>
  
  <pre><code>`oauth2client.client.CryptoUnavailableError: No crypto library available`
  </code></pre>
  
  <p>After doing a little research I found that this might have to do with granting the app domain-wide authority to the service account. However, when I log on to the Google Developers Console I cannot locate the security icon or the more-options button. Any help much appreciated thank you. </p>
