I know what I can decrypt data then recreate key(with all parammeters supplied) and encrypt data with a new key.But it would be great to find another solution. I tried to create it with the same sql query as above, but decryption in this case returns NULL. Create the Database Encryption Key or Symmetric Key in the User Database Enable Database for Encryption Take a Backup of the Master Key and Certificate. I import table with data from the old database.Īnd there is a question: Is there any way to create the same encryption key in the new database without specifying key_source and the identity_value? (Because I don't have it) The key in the old database has been created with the next sql script: CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'TESTPSWD'ĬREATE CERTIFICATE WITH SUBJECT = 'Key Protection' ĮNCRYPTION BY CERTIFICATE Īnd now I have to move this table with all data to the new database. While this isnt required to encrypt the database, you want to do this immediately. Backing up the certificate and the certificates private key. Creating a certificate encrypted by that key. It consists of: Creating the database master key in the master database. So, I am trying to understand in what scenarios do we have to create the same service master key and database master key. The Master Key is used to protect all your certificates private and asymmetric keys of each TDE database. Configuring a SQL Server database for TDE is a straight-forward process. I have table in the first(old) database with encrypted column.(The table contains encrypted data) the master key is generate by password and if we want to restore the database on new server, we need to recreate the certificate. I have an issue with symmetric key restoring on the another database.
