ICspStatuses::get_ItemByProvider method (certenroll.h)

The ItemByProvider property retrieves an ICspStatus object that has the same name as the provider specified on input but identifies an algorithm that supports a different intended key use.

This property is read-only.

Syntax

HRESULT get_ItemByProvider(
  ICspStatus *pCspStatus,
  ICspStatus **ppValue
);

Parameters

pCspStatus

ppValue

Return value

None

Remarks

The ItemByProvider property retrieves the ICspStatus object that matches the name of the input provider but is associated with a different X509KeySpec enumeration value. For example, if the input provider has a KeySpec value of XCN_AT_KEYEXCHANGE, the ItemByProvider property attempts to find an ICspStatus object for the same provider but with a KeySpec value of XCN_AT_SIGNATURE.

Because the KeySpec property is only associated with legacy providers, if you specify a Cryptography API: Next Generation (CNG) providers, the ItemByProvider property returns the same ICspStatus object as that entered.

To use this property to iterate through the collection, perform the following steps:

• Retrieve an ICspStatuses collection by calling the GetCspStatuses method or the CspStatuses property on the IX509CertificateRequestPkcs10 interface.
• Call the ItemByIndex property to iterate through the collection.
• For each ICspStatus element retrieved that contains the provider you are interested in, call ItemByProvider.
