Decrypts the specified encrypted key using the specified cryptographic algorithm.
public:
override cli::array <System::Byte> ^ DecryptKey(System::String ^ algorithm, cli::array <System::Byte> ^ keyData);
public override byte[] DecryptKey (string algorithm, byte[] keyData);
override this.DecryptKey : string * byte[] -> byte[]
Public Overrides Function DecryptKey (algorithm As String, keyData As Byte()) As Byte()
Parameters
- algorithm
- String
The cryptographic algorithm to decrypt the key.
Returns
An array of Byte that contains the decrypted key.
Exceptions
The X.509 certificate specified in the constructor does not have a private key.
-or-
The X.509 certificate has a private key, but it was not generated using the RSA algorithm.
-or-
The X.509 certificate has a private key, it was generated using the RSA algorithm, but the KeyExchangeAlgorithm property is null
.
-or-
The algorithm
parameter is not supported. The supported algorithms are XmlEncRSA15Url and XmlEncRSAOAEPUrl.
Remarks
Use the XmlEncRSA15Url or XmlEncRSAOAEPUrl fields to specify the algorithm.
