oauth2_proxy_authentication gem

NOTE: This gem will not work until after bitly/oauth2_proxy#147 is integrated.

Authenticates requests from bitly/oauth2_proxy based on a shared-secret HMAC signature of the request.

If you're using Bundler in your project, add the following to your Gemfile:

gem 'oauth2_proxy_authentication'

If you're not using Bundler, start.

Inject something resembling the following code fragment into your request handling logic as the first thing that happens before the request body is parsed, where secret_key is the shared secret between your application and the running instance of bitly/oauth2_proxy:

def my_handler(request)
  result, header_signature, computed_signature = (
    Oauth2ProxyAuthentication.validate_request(request, secret_key))
  if result != Oauth2ProxyAuthentication::MATCH
    # Cancel the request, optionally logging the values above.
  end
end
