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

Adding Google Sign In With Rails and React

For this blog post we will be using ruby version 2.4.0 and rails version 5.1.4 as backend and React/Redux as frontend. Adding Google Sign in functionality in your application can be done in two popular ways.

  • Adding google sign in functionality in the frontend with google api client gapi.

  • Adding google sign in functionality logic in the backend server.

If your application has separate backendend with APIs feeding data to the frontend React application, I suggest you to follow the step 2. If you want yo enhance your application security, then you implement both.
