title: MASTER KEY NOT GENERATED RAILS 6
body: <p>I have scaffolded a rails application (v6.0.3.4), after one day I realised that the master key wasn’t there.
  I know I can generate it, but it wouldn’t be the 'original', as I understand it.</p>
  <p>Is it any possibility that the master key is there and I need a command to make it visible ?
  Is there any other solution than scaffolding again?</p>
