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 */
