<HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort := True)> _

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.

The CngProvider class is a utility class. It consists of static properties, comparison methods, and a private, internally maintained string that specifies a key storage provider.

The static properties return CngProvider objects. Each object's internal string is initialized to the provider name that corresponds to the name of the static property.

You can also use this class to create objects for provider types that are not covered by the static properties.

Several CNG classes (such as CngKey) accept CngProvider objects through a provider parameter. When the class receives the CngProvider object, it retrieves the embedded provider name by calling the object's Provider property.

Therefore, CngProvider serves as an enumeration of well-known providers. It lets you identify a provider by using a strongly typed value instead of a string.
