CERT_EXTENSION structure (wincrypt.h)
The CERT_EXTENSION structure contains the extension information for a certificate, Certificate Revocation List (CRL) or Certificate Trust List (CTL).
Syntax
typedef struct _CERT_EXTENSION {
LPSTR pszObjId;
BOOL fCritical;
CRYPT_OBJID_BLOB Value;
} CERT_EXTENSION, *PCERT_EXTENSION;
Members
pszObjId
Object identifier (OID) that specifies the structure of the extension data contained in the Value member. For specifics on extension OIDs and their related structures, see X.509 Certificate Extension Structures.
fCritical
If TRUE, any limitations specified by the extension in the Value member of this structure are imperative. If FALSE, limitations set by this extension can be ignored.
Value
A CRYPT_OBJID_BLOB structure that contains the encoded extension data. The cbData member of Value indicates the length in bytes of the pbData member. The pbData member byte string is the encoded extension.
