CngPropertyOptions Enumeration

Specifies Cryptography Next Generation (CNG) key property options.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Namespace:  System.Security.Cryptography
Assembly:  System.Core (in System.Core.dll)

[FlagsAttribute]
public enum CngPropertyOptions

Member nameDescription
CustomPropertyThe property is not specified by CNG. Use this option to avoid future name conflicts with CNG properties.
NoneThe referenced property has no options.
PersistThe property should be persisted.

These options are used to initialize CngProperty objects, which are then used in SetProperty calls. You also use these options when you query for the value of properties with the GetProperty method.

Properties must be queried with the CngPropertyOptions they are stored with. Otherwise, they will not be found.
