Just use step4 from case1 to change the password and follow the procedure in step 1. In case if you are not aware about the password and source is accessible. Step 4: - if you want to change database master key encryption password the you need to complete the following step Case 2: When database master key encryption password is unknown. Step 3: - Check if you can decrypt the data without opening the key with password and answer is yes because key is now also encrypted by current service master key. Step 2: - One of the questions that come to mind is the possibility of opening the key with password in every session or you can hardcode this? Answers is no, in such cases, you will re-encrypt the database master key with current instance service master key and run the following commands as shown in the snapshot. Step 1: - Open database master key using password and decrypt the data. Case 1 - When database master key encryption password is known. This will not give you any error however functionality will be impacted due to missing encryption keys.Īs we did not open the database master key hence decryption of data is not possible, also DMK is not encrypted by current instance service master key hence you see such issue, we have many solutions to resolve this, so let’s talk about them one by one.
When you are encrypting data within the cell using certificate or keys, this is known as CLE (Cell Level Encryption).
When we are encrypting sensitive data, there are many ways to achieve this in MS SQL Server like CLE, TDE, and Always Encrypted. ĭata security is one of the critical aspect in database management. In this blog, I have discussed the necessary steps for restoring database and retrieving encrypted data when CLE (Cell Level Encryption) is implemented.
