IX509CertificateRequestPkcs10::get_NullSigned method (certenroll.h)

The NullSigned property retrieves a Boolean value that indicates whether 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 PKCS #10 certificate request is not really signed. That is, the signature is a hash created by using a digest algorithm such as SHA-1, but the request 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. For more information, see the InitializeFromPublicKey method.

You must initialize the IX509CertificateRequestPkcs10 object before calling this property. For more information, see any of the following methods:

• InitializeDecode
• InitializeFromCertificate
• InitializeFromPrivateKey
• InitializeFromPublicKey
• InitializeFromTemplateName
