IX509SignatureInformation::get_NullSigned method (certenroll.h)
The NullSigned property specifies and retrieves a Boolean value that indicates whether the certificate request is null-signed.
This property is read/write.
Syntax
HRESULT get_NullSigned(
VARIANT_BOOL *pValue
);
Parameters
pValue
Return value
None
Remarks
A null-signed certificate request is not really signed. That is, the request can be digested by using a digest algorithm such as SHA-1, but it is not encrypted with a public key algorithm such as RSA. You must set this property before calling the GetSignatureAlgorithm method.
