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

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

public override ICryptoTransform GetDecryptionTransform(
	string algorithm,
	byte[] iv
)

Parameters

algorithm
Type: System.String

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

iv
Type: System.Byte[]

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

Return Value

Type: System.Security.Cryptography.ICryptoTransform

An ICryptoTransform that represents the decryption transform.

Exception Condition
InvalidOperationException

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

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