Module name & Sandbox page: Hawk Auth
Hawk authentication is a module which provides Hawk protocol integration for Drupal 8. It's an alternative to OAuth based authentication and can be useful since it's simpler to handle.
Currently Hawk doesn't have any clients for testing purposes, one needs to write a script (for example with cURL) in order to be able to test it. I tested it with Drupal's REST module since that's where my primary focus was.
git clone --branch 8.x-1.x http://git.drupal.org/sandbox/Dragooon/2499839.git hawk_auth cd hawk_auth
