CertSetEnhancedKeyUsage function (wincrypt.h)
The CertSetEnhancedKeyUsage function sets the enhanced key usage (EKU) property for the certificate. Use of this function replaces any EKUs associated with the certificate. To add a single EKU usage without changing existing usages, use CertAddEnhancedKeyUsageIdentifier. To delete a single EKU usage, use CertRemoveEnhancedKeyUsageIdentifier.
Syntax
BOOL CertSetEnhancedKeyUsage(
[in] PCCERT_CONTEXT pCertContext,
[in] PCERT_ENHKEY_USAGE pUsage
);
Parameters
[in] pCertContext
A pointer to the CERT_CONTEXT of the specified certificate.
[in] pUsage
Pointer to a CERT_ENHKEY_USAGE structure (equivalent to a CTL_USAGE structure) that contains an array of EKU object identifiers (OIDs) to be set as extended properties of the certificate.
Return value
If the function succeeds, the function returns nonzero (TRUE).
If the function fails, it returns zero (FALSE). For extended error information, call GetLastError.
