  /* 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

     for interpretation.  I've done tests against another responder, and found

     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 */
