Checking Certificate Revocation
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
When importing content into Windows Media DRM, you must ensure that no certificate in a certificate collection has been revoked by verifying that no certificate in the collection is in the revocation list. The revocation list is extracted by using the IWMDRMSecurity::GetRevocationData method.
You then use the IWMDRMSecurity::CheckCertForRevocation method to verify that the certificate is not revoked.
