SQL SERVICE MASTER KEY CODE
SQL SERVICE MASTER KEY PASSWORD

The fact that you create a new key with the same name is not going to help. If you are new to encryption and want to get a head start, this book by MVP colleagues Michael Coles and Rodney Landrum may be useful to you: Д®rland Sommarskog, SQL Server MVP, haven't tested this, and I have not worked that much with encryption in SQL Server.Д«ut reasonably, if you want to encrypt on one server and decrypt on another server, one of the following must apply:ДЎ) Both servers must have the same service master key.Дў) At some point you must open a key through a password.ДЄs I understand your post, you delete the key in the restored database, and at that point you have lost all possibilities to decrypt the data.

However, you will need to open the master key first (to prove that you are authorised to use the master key). You can use ALTER MASTER KEY to change the master key so that it is encrypted by the service master key of the new server:ДЄLTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY

OPEN MASTER KEY DECRYPTION BY PASSWORD = '23987hxJKL969#ghf0%94467GRkjg5k3fd117r$$#1946kcj$n44nhdlj' EXEC ReadDecryptedPwd 'Someuser' Therefore, to use the database master key on the new server, you will need do open it first, by using the password. As long as you are on the source server, you don't need to open the database master key, since the service master key is there for you.Д«ut if you move the database to a different server, that server has a different master key. The data will be lost.ДЄ database master key can be protected by a password of by the service master key. But if all keys for whatever reason have been lost at this point, it will not help to create new keys at this point. The IF statement checks for the database master key.

Note that the procedure for decryption has a piece of code that is questionable:
