The DEK is stored in the database itself and you can have only one DEK in each database. This key is protected by the certificate generated at the steps above. Now you need to create the main key, which is the Database Encryption Key (DEK). TO FILE = 'C:\CertBackup\ImagicleDEKCertificate.cer'įILE = 'C:\CertBackup\ImagicleCertPrivateKey.key', BACKUP CERTIFICATE MyImagicleDBCertificate This task, even though not mandatory, is very important, because if the certificate gets lost, all the encrypted data are lost and there will be no way to recover them. USE master ĬREATE CERTIFICATE MyImagicleDBCertificate WITH SUBJECT= 'Imagicle DEK Certificate' Backup Certificate This certificate protects the the Database Encryption Key (DEK) created in the next steps. Now you should create the certificate which is protected by previously generated Database Master Key. USE master CREATE MASTER KEY ENCRYPTION BY PASSWORD = '' Create Certificate Thanks to this key, you can encrypt all the encryptable objects within the database, such as Symmetric Keys, Asymmetric Keys and Certificates. The first task implies Database Master Key (DMK) creation, which is a symmetric key to protect other keys. Backup Certificate ( not mandatory, but strongly suggested). ![]() This is the procedure summary to apply TDE encryption to the Imagicle database:
