SecurityKeyElement.DecryptKey Method

[Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework. The version of WIF addressed by this topic, WIF 3.5, is deprecated and should only be used when developing against the .NET Framework 3.5 SP1 or the .NET Framework 4. For more information about WIF in the .NET Framework 4.5, also known as WIF 4.5, see the Windows Identity Foundation documentation in the .NET Framework 4.5 Development Guide.]

Decrypts a key using the specified algorithm.

Namespace: Microsoft.IdentityModel.Tokens
Assembly: Microsoft.IdentityModel (in Microsoft.IdentityModel.dll)


Dim instance As SecurityKeyElement
Dim algorithm As String
Dim keyData As Byte()
Dim returnValue As Byte()
