Retrieves the decryption initialization vector (IV) from an EncryptedData object.

override this.GetDecryptionIV : System.Security.Cryptography.Xml.EncryptedData * string -> byte[]Public Overridable Function GetDecryptionIV (encryptedData As EncryptedData, symmetricAlgorithmUri As String) As Byte()Parameters
- encryptedData
- EncryptedData
The EncryptedData object that contains the initialization vector (IV) to retrieve.
- symmetricAlgorithmUri
- String
The Uniform Resource Identifier (URI) that describes the cryptographic algorithm associated with the encryptedData value.
Returns
A byte array that contains the decryption initialization vector (IV).
Exceptions
The value of the encryptedData parameter is null.
The value of the encryptedData parameter has an EncryptionMethod property that is null.
-or-
The value of the symmetricAlgorithmUrisymAlgUri parameter is not a supported algorithm.
Remarks
Given an EncryptedData object, this method retrieves the decryption initialization vector (IV). The default behavior retrieves the IV as the first bytes of the CipherValue byte array.
For a list of Uniform Resource Identifier (URI) values supported by the symmetricAlgorithmUri parameter, see the list of constant fields associated with the EncryptedXml class.
