What I need to know about Rails 6 credentials and master key
The credentials are stored in the "credentials.yml.enc" file, encrypted.
To decrypt the credentials file, you need a master key that is set on either:
* config/master.key file (for local development)
* ENV["RAILS_MASTER_KEY"] (for deployed environments)
What should you commit?
* The file config/master.key should be ignored in gitignore (you should not commit the master key)
* The file credentials.yml.enc should be commited along with the codebase (but don't worry, only those who have the master key can decrypt it)
