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
