This class enables you to create a UI policy for displaying prompts about key operations such as smart card PIN prompts. It also enables you to enforce user interaction to access a key, even if the key is stored in a software key storage provider (KSP) instead of in a smart card. CNG displays these configuration parameters for the UI when you access a protected key.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser).
