How to regenerate the master key for Rails 5.2 credentials

If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

  1. Copy content of original credentials rails credentials:show somewhere temporarily.
  2. Remove config/master.key and config/credentials.yml.enc
  3. Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
  4. Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
  5. Add and Commit the file config/credentials.yml.enc
