WebApr 13, 2024 · The key is a secret value that both the sender and the receiver of the data must know and keep secure. Symmetric encryption is fast, simple, and efficient, as it requires less computational power ... WebStep 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.
