  • Reference

Definition

Namespace:
System.Data.SqlClient
Assembly:
System.Data.dll

Decrypts the specified encrypted value of a column encryption key. The encrypted value is expected to be encrypted using the certificate with the specified key path and using the specified algorithm. The format of the key path should be "Local Machine/My/<certificate_thumbprint>" or "Current User/My/<certificate_thumbprint>".

public:
 override cli::array <System::Byte> ^ DecryptColumnEncryptionKey(System::String ^ masterKeyPath, System::String ^ encryptionAlgorithm, cli::array <System::Byte> ^ encryptedColumnEncryptionKey);
public override byte[] DecryptColumnEncryptionKey (string masterKeyPath, string encryptionAlgorithm, byte[] encryptedColumnEncryptionKey);
override this.DecryptColumnEncryptionKey : string * string * byte[] -> byte[]
Public Overrides Function DecryptColumnEncryptionKey (masterKeyPath As String, encryptionAlgorithm As String, encryptedColumnEncryptionKey As Byte()) As Byte()

Parameters
