Definition

Namespace:

System.IdentityModel.Tokens

Assembly:

System.IdentityModel.dll

Gets the size, in bits, of the initialization vector (IV) that is required for the specified cryptographic algorithm.

public:
 override int GetIVSize(System::String ^ algorithm);

public override int GetIVSize (string algorithm);

override this.GetIVSize : string -> int

Public Overrides Function GetIVSize (algorithm As String) As Integer

Parameters

algorithm

String

The cryptographic algorithm to get the size of the initialization vector (IV).

Returns

Int32

The size, in bits, of the initialization vector (IV) that is required for the cryptographic algorithm specified in the algorithm parameter.

Exceptions

InvalidOperationException

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

Remarks

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