SQL Server has two primary applications for keys: a service master key (SMK) generated on and for a SQL Server instance, and a database master key (DMK) used for a database. Service master key The Service Master Key is the root of the SQL Server encryption hierarchy. The SMK is automa...
每當DMK 變更時,也會以無訊息模式更新儲存於 master 系統資料庫中的 DMK 複本。但是,此預設值可以使用 ALTER MASTER KEY 陳述式的 DROP ENCRYPTION BY SERVICE MASTER KEY 選項來加以變更。未以服務主要金鑰加密的 DMK 必須使用 OPEN MASTER KEY 陳述式和密碼來開啟。
