CngUIPolicy Class

Encapsulates optional configuration parameters for the user interface (UI) that Cryptography Next Generation (CNG) displays when you access a protected key.

Namespace:  System.Security.Cryptography
Assembly:  System.Core (in System.Core.dll)
[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public sealed class CngUIPolicy
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). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

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.
