OCSP_SIGNED_REQUEST_INFO structure (wincrypt.h)
The OCSP_SIGNED_REQUEST_INFO structure contains information for an online certificate status protocol (OCSP) request with optional signature information.
Syntax
typedef struct _OCSP_SIGNED_REQUEST_INFO {
CRYPT_DER_BLOB ToBeSigned;
POCSP_SIGNATURE_INFO pOptionalSignatureInfo;
} OCSP_SIGNED_REQUEST_INFO, *POCSP_SIGNED_REQUEST_INFO;
Members
ToBeSigned
A BLOB that has been encoded by using Distinguished Encoding Rules (DER) and that contains the OCSP request information.
pOptionalSignatureInfo
A pointer to an OCSP_SIGNATURE_INFO structure that contains optional signature information.
Remarks
In an OCSP client application, this structure receives an encoded OCSP_REQUEST_INFO structure as its ToBeSigned member. Optionally, a signature of the ToBeSigned member is stored in the pOptionalSignatureInfo member.
On the receiving end, an OCSP responder application decodes the incoming request to populate an OCSP_SIGNED_REQUEST_INFO structure and subsequently decodes the ToBeSigned member to obtain an OCSP_REQUEST_INFO structure.
OCSP applications can encode or decode this structure by using X509_ASN_ENCODING or PKCS_7_ASN_ENCODING.
