CERT_CHAIN_ELEMENT structure (wincrypt.h)
The CERT_CHAIN_ELEMENT structure is a single element in a simple certificate chain. Each element has a pointer to a certificate context, a pointer to a structure that indicates the error status and information status of the certificate, and a pointer to a structure that indicates the revocation status of the certificate.
Syntax
typedef struct _CERT_CHAIN_ELEMENT {
DWORD cbSize;
PCCERT_CONTEXT pCertContext;
CERT_TRUST_STATUS TrustStatus;
PCERT_REVOCATION_INFO pRevocationInfo;
PCERT_ENHKEY_USAGE pIssuanceUsage;
PCERT_ENHKEY_USAGE pApplicationUsage;
LPCWSTR pwszExtendedErrorInfo;
} CERT_CHAIN_ELEMENT, *PCERT_CHAIN_ELEMENT;
Members
cbSize
Size of this structure in bytes.
pCertContext
A pointer to a certificate context.
TrustStatus
Structure indicating the status of the certificate. The structure includes an error status code and an information status code. For information about status code values, see CERT_TRUST_STATUS.
pRevocationInfo
A pointer to a CERT_REVOCATION_INFO structure with information on the revocation status of the certificate. If revocation checking was not enabled, pRevocationInfo is NULL.
pIssuanceUsage
A pointer to a CERT_ENHKEY_USAGE structure. If NULL, any issuance policy is acceptable.
pApplicationUsage
A pointer to a CERT_ENHKEY_USAGE structure. If NULL, any enhanced key usage is acceptable.
pwszExtendedErrorInfo
A pointer to a null-terminated wide character string that contains extended error information. If NULL, there is no extended error information.
