WebJan 5, 2024 · Step 1 Creating a Database Master Key. Before creating any certificates or other keys, a Database Master Key must be created. A database “master key” is a symmetric key used to protect asymmetric keys in a database. When it is created, the master key is encrypted by using the AES_256 algorithm and a user-supplied password. WebMar 23, 2024 · It is a symmetric key and supported algorithms are AES with 128-bit, 192bit, or 256bit keys or 3 Key Triple DES. Once TDE is enabled on a database then the DEK is used to encrypt the contents of the database and the log. When TDE is enabled for any database on the server, TempDB is also encrypted and its DEK is managed internally by SQL Server.
