Code snippet to show how to verify Firebase ID tokens using Ruby.
FirebaseIDTokenVerifier class holds 2 methods: encode and decode.
The encode method is written just for testing purpose - I have other project where I use this method in my tests to generate a test JWT token and use it in further tests.
The decode method is actually what you need. It helps you to verify your Firebase ID token according to Firebase validation rules: Verify ID tokens using a third-party JWT library
