IX509CertificateRequestCmc::get_NullSigned method (certenroll.h)

  • Article

The NullSigned property retrieves a Boolean value that specifies whether the primary signature on the certificate request is null-signed.

This property is read-only.

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. This can be used when a private key is not available as is often the case when certification authorities are being cross-certified.

You must initialize the CMC request object before calling this property. For more information, see the following topics:
