The CertSetEnhancedKeyUsage function sets the enhanced key usage property for the certificate.
#include <wincrypt.h>
BOOL WINAPI CertSetEnhancedKeyUsage(
PCCERT_CONTEXT pCertContext, // in
PCERT_ENHKEY_USAGE pUsage // in
);
TRUE if the function succeeded, FALSE if the function failed.
Call GetLastError to see the reason for any failures.
// EXAMPLE CODE FOR USING CertSetEnhancedKeyUsage.
// Sets the enhanced key usage property for the certificate.
// Assume that a pointer to the certificate (pCertContext) and a
// pointer to the key usage information (pUsage) is already known.
// Set up the variables.
PCCERT_CONTEXT pCertContext; // Initialized elsewhere.
PCERT_ENHKEY_USAGE pUsage; // Initialized elsewhere.
BOOL fResult; // Returned TRUE if function successful.
// False if function failed
fResult = CertSetEnhancedKeyUsage(
pCertContext, // in - Pointer to the certificate
pUsage); // in - Pointer to the key usage
// identifier
if (!fResult) { // FALSE
cout<< "functional failed"<< endl
<< "error code = "<< GetLastError ()<< endl;
}
else { // TRUE
cout<< "function succeeded"<< endl;
