Description
The lib/hooks/plugins/auth/hmac.rb file has gotten quite large and unwieldy. Please check it out and ensure it follows ruby best practices, is clean and concise. Ensure that all logic related to timestamp parsing is clean and easily testable.
A lot of the logic related to timestamps has gotten quite messy. It should be evaluated to become more maintainable. Do not break any existing logic. Also cleanup the hmac tests to be more DRY and concise as well. They have gotten quite long.
