title: Why I can not use a ready-made credentials?
body: <p>I want to use ready-made credential, that are on my server.</p>
  
  <p>I do <code>EDITOR="nano --wait" bin/rails credentials:edit</code></p>
  
  <p>Then I replace the contents of credentials.yml.enc and master.key with the ones inside these files on my server.
  But when I try to read credentials I get an error <code>Couldn't decrypt config/credentials.yml.enc. Perhaps you passed the wrong key?</code></p>
