.with_deep_deundescored_keys(hash) ⇒ Object

This will look for any keys that starts with an underscore and duplicates that key-value pair but without the starting underscore. So “abab” will become “abab”, a: “abab” This so we can easilly access our unencrypted secrets without having to add an underscore
