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

'Declaration
<HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort := True)> _
Public NotInheritable Class SHA256Cng _
	Inherits SHA256
'Usage
Dim instance As SHA256Cng

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 algorithm is for hashing only and does not provide any encryption or decryption. It uses the BCrypt (BestCrypt) layer CNG.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
