Provides a workaround for the .NET Framework version 2.0 implementation of the HMACSHA512 algorithm, which is inconsistent with the .NET Framework version 2.0 Service Pack 1 implementation.
(in mscorlib.dll)
Visual Basic (Declaration)
Public Property ProduceLegacyHmacValues As Boolean
Dim instance As HMACSHA512
Dim value As Boolean
value = instance.ProduceLegacyHmacValues
instance.ProduceLegacyHmacValues = value
public bool ProduceLegacyHmacValues { get; set; }
public:
property bool ProduceLegacyHmacValues {
bool get ();
void set (bool value);
}
public function get ProduceLegacyHmacValues () : boolean
public function set ProduceLegacyHmacValues (value : boolean)
Property Value
Type:
System..::.Boolean
true to enable .NET Framework version 2.0 Service Pack 1 applications to interact with .NET Framework 2.0 applications; otherwise, false.
The purpose of the ProduceLegacyHmacValues Boolean property is to enable .NET Framework version 2.0 Service Pack 1 applications to interact with .NET Framework 2.0 applications. When you set this property to true, the HMACSHA512 object produces values that match the values produced by the .NET Framework 2.0. You should set this property only once after you create your HMAC object. You will need to reset your key afterwards, as shown in the following example.
public static void Test()
{
HMACSHA512 hmac = new HMACSHA512();
hmac.ProduceLegacyHmacValues = true;
hmac.Key = // ...Get the HMAC key.
// ...
// Use the HMAC algorithm.
// ...
}
For additional information about the changes introduced by .NET Framework 2.0 SP1 to support HMACSHA512 output in the .NET Framework 2.0 environment, see the HMACSHA512 class.
Windows 7, Windows Vista, Windows XP SP2, Windows Server 2008 R2, Windows Server 2008, Windows Server 2003
The .NET Framework and .NET Compact Framework do not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
