+ * Attribute. But the cert request template does not treat the
+ * Attributes as a SET OF ANY, and AFAIK never has. Instead the template
+ * encodes attributes as a SET OF xxxxxxx. That is, it expects to encode
+ * each of the Attributes, not have them pre-encoded. Consequently an
+ * array of SECItems containing encoded Attributes is of no value to this
+ * function. But we cannot change the signature of this public function.
+ * It must continue to take SECItems.
+ *
+ * I have recoded this function so that each SECItem contains an
+ * encoded cert extension. The encoded cert extensions form the list for the
+ * single attribute of the cert request. In this implementation there is at most
+ * one attribute and it is always of type SEC_OID_PKCS9_EXTENSION_REQUEST.

+ * If NULL, result will be allocated from the heap (and thus should

+ * const char *location

+ * const char *method
+ * The protocol method used when retrieving the OCSP response.
+ * Currently support: "GET" (http GET) and "POST" (http POST).
+ * Additionals methods for http or other protocols might be added

+ * but has no other bearing on the operation.
+ * PRBool addServiceLocator
+ * If true, the Service Locator extension should be added to the

+ * If non-NULL, means sign the request using this cert. Otherwise,

+ * OUTPUTS:
+ * CERTOCSPRequest **pRequest
+ * Pointer in which to store the OCSP request created for the given

+ * is successful and the pointer is not null -- and in that case the

+ * that must be checked individually for each certificate.
+ * INPUTS:
+ * CERTOCSPResponse *response
+ * Pointer to response structure with signature to be checked.
+ * CERTCertDBHandle *handle
+ * Pointer to CERTCertDBHandle for certificate DB to use for verification.
+ * void *pwArg
+ * Pointer to argument for password prompting, if needed.
+ * OUTPUTS:
+ * CERTCertificate **pSignerCert
+ * Pointer in which to store signer's certificate; only filled-in if
+ * non-null.
+ * RETURN:
+ * Returns SECSuccess when signature is valid, anything else means invalid.
+ * Possible errors set:
+ * SEC_ERROR_OCSP_MALFORMED_RESPONSE - unknown type of ResponderID
+ * SEC_ERROR_INVALID_TIME - bad format of "ProducedAt" time
+ * SEC_ERROR_UNKNOWN_SIGNER - signer's cert could not be found
+ * SEC_ERROR_BAD_SIGNATURE - the signature did not verify
+ * Other errors are any of the many possible failures in cert verification
+ * (e.g. SEC_ERROR_REVOKED_CERTIFICATE, SEC_ERROR_UNTRUSTED_ISSUER) when
+ * verifying the signer's cert, or low-level problems (no memory, etc.)

+ * The public data types all start with "CERTOCSP" (e.g. CERTOCSPRequest).
+ * (Even the public types are opaque, however. Only their names are

+ *
+ * Internal-only data types drop the "CERT" prefix and use only the
+ * lower-case "ocsp" (e.g. ocspTBSRequest), for brevity sake.
+ *
+ * In either case, the base/suffix of the type name usually matches the
+ * name as defined in the OCSP specification. The exceptions to this are:
+ * - When there is overlap between the "OCSP" or "ocsp" prefix and
+ * the name used in the standard. That is, you cannot strip off the
+ * "CERTOCSP" or "ocsp" prefix and necessarily get the name of the
+ * type as it is defined in the standard; the "real" name will be
+ * *either* "OCSPSuffix" or just "Suffix".
+ * - When the name in the standard was a little too generic. (e.g. The
+ * standard defines "Request" but we call it a "SingleRequest".)
+ * In this case a comment above the type definition calls attention
+ * to the difference.
+ *
+ * The definitions laid out in this header file are intended to follow
+ * the same order as the definitions in the OCSP specification itself.
+ * With the OCSP standard in hand, you should be able to move through
+ * this file and follow along. To future modifiers of this file: please
+ * try to keep it that way. The only exceptions are the few cases where
+ * we need to define a type before it is referenced (e.g. enumerations),
