  /* Note 1:
     The value for "signature" is specified in the OCSP rfc2560 as follows:
     "The value for the signature SHALL be computed on the hash of the DER
     encoding ResponseData."  This means that you must hash the DER-encoded
     tbsResponseData, and then run it through a crypto-signing function, which
     will (at least w/RSA) do a hash-'n'-private-encrypt operation.  This seems
     a bit odd, but that's the spec.  Also note that the data structures do not
     leave anywhere to independently specify the algorithm used for the initial
     hash. So, we look at the signature-specification algorithm, and try to do
     something intelligent.	-- Kathy Weinhold, CertCo */
  /* Note 2:
     It seems that the mentioned passage from RFC 2560 (section 4.2.1) is open

     that it doesn't do the double hashing that the RFC seems to say one
     should.  Therefore, all relevant functions take a flag saying which
     variant should be used.	-- Richard Levitte, OpenSSL team and CeloCom */
