IWMDRMSecurity interface
[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 It has been superseded by Source Reader and Sink Writer.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.]
The IWMDRMSecurity interface manages a variety of security-related information for the client computer and digital rights management (DRM) subsystem.
To obtain an instance of this interface, call IWMDRMProvider::CreateObject. Pass IID_IWMDRMSecurity as the riid parameter.
