Public Overridable Function GetDecryptionKey (encryptedData As EncryptedData, symmetricAlgorithmUri As String) As SymmetricAlgorithm
The EncryptedData object that contains the decryption key to retrieve.
The size of the decryption key to retrieve.
A SymmetricAlgorithm object associated with the decryption key.
The value of the encryptedData
parameter is null
.
The encryptedData parameter has an EncryptionMethod property that is null.
-or-
The encrypted key cannot be retrieved using the specified parameters.
Given an EncryptedData object, this method looks for the decryption key that can be used to retrieve the plain text data. If a key name is specified, the method looks for the symmetric algorithm or asymmetric algorithm that is associated with the key name as defined in the key name mapping. Otherwise, if a retrieval method or an EncryptedKey object is specified, the method loads the EncryptedKey object and calls the GetDecryptionKey method.
