title: Where do I store the encryption key when encrypting in Django?
body: <p>I am creating a website using Django, my website will encrypt uploaded files and another user can then download the files unencrypted.</p>
  <p>It's pretty straightforward encrypting in python (I am using the cryptography python library), but where do I store the encryption key?</p>
  <p>I encrypt the files in case the database or source code has been compromised. Then I can't store the encryption key as a file or in the database.</p>
  <p>Where can I store the encryption key?</p>
