10/30/2023 0 Comments Backup service master keyThe first is part of the TO FILE clause and specifies where the backup will be stored. Like the BACKUP SERVICE MASTER KEY statement, the BACKUP MASTER KEY statement has just two "parameters". In the following article, we will generate a certificate and encrypt and decrypt the string using that certificate.Note that the word "database" is omitted from this statement to prevent confusion with the BACKUP DATABASE statement. Restore Database Master Key by password" specifies the password used to encrypt the database master key after it has been loaded into the database. Still, the only difference is that it is not encrypted automatically with the service master key. If there is no master key available in the database, then the following statement creates a new master key. We can restore the database master key by executing the following statement. If this key is deleted or corrupted, it is tough to decrypt those keys, and the encrypted data using those keys may be lost, so it is advisable to take a backup of the database master key. Back up Database Master Key database master key is used to encrypt other keys and certificates. Since we drop encryption by the service master key, we must explicitly open the database master key with a password. We can reset the above setting by executing the following command. Alter Database Master Key ALTER MASTER KEY DROP ENCRYPTION BY SERVICE MASTER KEY We can change this setting by altering the master key. The Is_master_key_encrypted_by_server column value of the TestDB database specifies that the service master key encrypts the master key. SELECT is_master_key_encrypted_by_server,* FROM sys.databases For that, execute the following statement. Now let's see how to check whether the service master key encrypts it. To enable the automatic decryption of the master key, a copy of the key is encrypted using the service master key and stored in the database and the master. USE TestDB GO CREATE MASTER KEY ENCRYPTION BY PASSWORD = database master key is a symmetric key used to protect the private keys of certificates and asymmetric keys in the database. To create a Database Master Key, first, create the database "TestDB" in SQL Server and execute the following commands. In this article, we will discuss Database Master Key. Before this article, I highly recommend reading Encrypt & Decrypt in SQL Server Part-1.
