We’re looking for encryption_state = 3 (Encrypted). We can check the ecryption status with this query. So if I were to try to attach the database anywhere where I don’t have the keys and certificates, it’s not going to be readable. I’ve taken a copy of AdventureWorks and turned on TDE.

USE master ĬREATE MASTER KEY ENCRYPTION BY PASSWORD = '' ĬREATE CERTIFICATE MyServerCert WITH SUBJECT = 'My DEK Certificate' ĮNCRYPTION BY SERVER CERTIFICATE MyServerCert I already have set up replication, now let’s set up TDE. I have a few virtual machines running: SQLSERVERA is my publisher where I’m replicating from, SQLSERVERB will be my subscriber, and SQLSERVERC will be my distributor. The first happens with the replication snapshot. There’s a couple different ways reapplication will “break” TDE. And unless you like failing data security audits, you need to get a handle on it quickly. But there’s a dark side to TDE, and that’s when you combine it with replication: it essentially undoes all your hard work. So guess which one gets used more? In terms of set up and ease of use, TDE is a lot easier to maintain. The data is completely unreadable to anyone else not even the DBAs can read it. Always Encrypted is more work for the developers, since they need to work with the required libraries to make it work and handle the problem of keeping the certificates up to date and installed on the clients. It puts the onus on the DBAs to create certificates and store them inside SQL Server. In terms of setting each solution up, TDE is a lot easier.

So not only is the data encrypted on disk, it’s gibberish to anyone who doesn’t have the right certificates. If you want to view the data, you need an application with appropriate encryption libraries loaded AND certificates. Essentially, you don’t trust anyone with access to the server with your data, including the DBAs. It doesn’t require any configuration on the client side, all the translation and decryption happens on SQL Server. The theory goes, if the disks or underlying hardware were stolen out from under you then your data is secure so long as you keep your certificates in a safe place. However, on your storage, the data is encrypted. For anyone who has access, the data looks exactly “normal” when you query it. Transparent Data Encryption (TDE): TDE is encryption at rest.Most often, two technologies bubble up to the top of the heap:

If you want to (or more likely need to) encrypt data in SQL Server, you have options.
