Article

[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.]

Use this constructor if you want to send a combined entropy.

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

Usage

'Usage
Dim keySizeInBits As Integer
Dim targetWrappingCredentials As EncryptingCredentials
Dim requestorWrappingCredentials As EncryptingCredentials
Dim sourceEntropy As Byte()

Dim instance As New SymmetricProofDescriptor(keySizeInBits, targetWrappingCredentials, requestorWrappingCredentials, sourceEntropy)

Syntax

'Declaration
Public Sub New ( _
    keySizeInBits As Integer, _
    targetWrappingCredentials As EncryptingCredentials, _
    requestorWrappingCredentials As EncryptingCredentials, _
    sourceEntropy As Byte() _
)

public SymmetricProofDescriptor (
    int keySizeInBits,
    EncryptingCredentials targetWrappingCredentials,
    EncryptingCredentials requestorWrappingCredentials,
    byte[] sourceEntropy
)

public:
SymmetricProofDescriptor (
    int keySizeInBits, 
    EncryptingCredentials^ targetWrappingCredentials, 
    EncryptingCredentials^ requestorWrappingCredentials, 
    array<unsigned char>^ sourceEntropy
)

public SymmetricProofDescriptor (
    int keySizeInBits, 
    EncryptingCredentials targetWrappingCredentials, 
    EncryptingCredentials requestorWrappingCredentials, 
    byte[] sourceEntropy
)

public function SymmetricProofDescriptor (
    keySizeInBits : int, 
    targetWrappingCredentials : EncryptingCredentials, 
    requestorWrappingCredentials : EncryptingCredentials, 
    sourceEntropy : byte[]
)

Parameters

keySizeInBits
The size of the symmetric key.

targetWrappingCredentials
The key encrypting credentials for the target of the request.

requestorWrappingCredentials
The encrypting credentials for the requestor used to encrypt the entropy or the proof token

sourceEntropy
The requestor's entropy.

Exceptions

Exception type	Condition
ArgumentNullException	The source entorpy is null or is an empty array.
ArgumentOutOfRangeException	The key size is less than zero.

Platforms

Target Platforms

Windows 7, Windows Server 2008 R2, Windows Vista SP2, Windows Server 2008 SP2, Windows Server 2003 SP2 (32-bit or 64-bit)
