CngKey objects contain properties. Some properties must be added to a key when it is created. Other properties can be added after the key is created.

The CngKeyCreationParameters class enables you to add properties to a key as it is being created. You can do this by passing a CngKeyCreationParameters object that contains standard key properties, such as key storage provider (KSP), export policy, key usage, user interface (UI) policy, and parent window handle, to the Create method. The CngKey object that is being created will be initialized with these values before it is finalized.

You can also add non-standard properties to a key by using the Parameters property.

If you need to add properties after a key is created, use the SetProperty method.

Note Note

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.
