#signature_info ⇒ Object

mauth_client will authenticate with the highest protocol version present and ignore other protocol versions. returns a hash with keys :token, :app_uuid, and :signature parsed from the MCC-Authentication header if it is present and if not then the X-MWS-Authentication header if it is present. Note MWSV2 protocol no longer allows more than one space between the token and app uuid.
