        Per `section 3.2`_ of the spec.

        - all mandated OAuth parameters are supplied
        - parameters are only supplied in one source which may be the URI
          query, the Authorization header or the body
        - all parameters are checked and validated, see comments and the
          methods and properties of this class for further details.
        - the supplied signature is verified against a recalculated one

        A ValueError will be raised if any parameter is missing,
        supplied twice or invalid. A HTTP 400 Response should be returned
        upon catching an exception.

        A HTTP 401 Response should be returned if verify_request returns False.

        `Timing attacks`_ are prevented through the use of dummy credentials to
        create near constant time verification even if an invalid credential
        is used. Early exit on invalid credentials would enable attackers
        to perform `enumeration attacks`_. Near constant time string comparison
        is used to prevent secret key guessing. Note that timing attacks can
        only be prevented through near constant time execution, not by adding
        a random delay which would only require more samples to be gathered.
