SafeNCryptProviderHandle Class

Definition

Provides a safe handle that represents a key storage provider (NCRYPT_PROV_HANDLE).

public ref class SafeNCryptProviderHandle sealed : Microsoft::Win32::SafeHandles::SafeNCryptHandle

Remarks

This class should be used when working with native code that expects an NCRYPT_PROV_HANDLE.

Important

This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try/catch block. To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.
