InMemorySymmetricSecurityKey.GetDecryptionTransform(String, Byte[]) Method

Definition

Namespace:

System.IdentityModel.Tokens

Assembly:

System.IdentityModel.dll

Gets a transform that decrypts cipher text using the specified cryptographic algorithm.

public:
 override System::Security::Cryptography::ICryptoTransform ^ GetDecryptionTransform(System::String ^ algorithm, cli::array <System::Byte> ^ iv);

public override System.Security.Cryptography.ICryptoTransform GetDecryptionTransform (string algorithm, byte[] iv);

override this.GetDecryptionTransform : string * byte[] -> System.Security.Cryptography.ICryptoTransform

Public Overrides Function GetDecryptionTransform (algorithm As String, iv As Byte()) As ICryptoTransform

Parameters

algorithm

String

A cryptographic algorithm that decrypts cipher text, such as encrypted XML.

iv

Byte[]

An array of Byte that contains the initialization vector (IV) for the specified algorithm.

Returns

ICryptoTransform

An ICryptoTransform that represents the decryption transform.

Exceptions

InvalidOperationException

algorithm is not supported. The supported algorithms are TripleDesEncryption, Aes128Encryption, Aes192Encryption, and Aes256Encryption.

Remarks

Use the fields that represent decryption algorithms in the SecurityAlgorithms class to specify the algorithm.
