C# Class System.Data.SqlClient.SqlColumnEncryptionKeyStoreProvider

Abstract base class for all column encryption Key Store providers. It exposes two functions 1. DecryptColumnEncryptionKey - This is the function used by SqlClient under the covers to decrypt encrypted column encryption key blob. 2. EncryptColumnEncryptionKey - This will be used by client tools that generate DDL for customers 3. SignColumnMasterKeyMetadata - This will be used by client tools that generate Column Master Keys (CMK) for customers 4. VerifyColumnMasterKeyMetadata - This will be used by SqlClient under the covers to verify the CMKs received from SQL Server

Méthode Description
DecryptColumnEncryptionKey ( string masterKeyPath, string encryptionAlgorithm, Array encryptedColumnEncryptionKey ) : byte[]

This function must be implemented by the corresponding Key Store providers. This function should use an asymmetric key identified by the key path and decrypt an encrypted column encryption key with a given encryption algorithm.
EncryptColumnEncryptionKey ( string masterKeyPath, string encryptionAlgorithm, Array columnEncryptionKey ) : byte[]

This function must be implemented by the corresponding Key Store providers. This function should use an asymmetric key identified by a key path and encrypt a plain text column encryption key with a given asymmetric key encryption algorithm.
