* 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
