278      encoding ResponseData."  This means that you must hash the DER-encoded
279      tbsResponseData, and then run it through a crypto-signing function, which
280      will (at least w/RSA) do a hash-'n'-private-encrypt operation.  This seems
281      a bit odd, but that's the spec.  Also note that the data structures do not
