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.

Copy content of original credentials rails credentials:show somewhere temporarily.
Remove config/master.key and config/credentials.yml.enc
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.
Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
Add and Commit the file config/credentials.yml.enc

Run rails new --help to view all of the options you can use to generate new Rails application:

Output for Rails 6+

  rails new APP_PATH [options]

Options:
      [--skip-namespace], [--no-skip-namespace]              # Skip namespace (affects only isolated applications)

Run rails new --help to view all of the options you can pass to rails new:

$ bin/rails new --help
Usage:
  rails new APP_PATH [options]
