SHA256Cng Class (System.Security.Cryptography)

.NET Framework Class Library

SHA256Cng Class

Provides a Cryptography Next Generation (CNG) implementation of the Secure Hash Algorithm (SHA) for 256-bit hash values.

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

Syntax

Visual Basic (Declaration)

<HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort := True)> _
Public NotInheritable Class SHA256Cng _
    Inherits SHA256

Visual Basic (Usage)

Dim instance As SHA256Cng

[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public sealed class SHA256Cng : SHA256

Visual C++

[HostProtectionAttribute(SecurityAction::LinkDemand, MayLeakOnAbort = true)]
public ref class SHA256Cng sealed : public SHA256

JScript

public final class SHA256Cng extends SHA256

Remarks

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.
