title: Keep Secret Keys Out
body: <p>One of the causes of the local_settings.py anti-pattern is that putting SECRET_KEY, AWS
  keys, etc.. values into settings files has problem:</p>
  
  <ul>
  <li>Secrets often should be just that: secret! Keeping them in version control means
  that everyone with repository access has access to them.</li>
  </ul>
  
  <p>My question is how to keep all keys as secret?</p>
