I’ll also brief about how to copy \ move the database that is encrypted with TDE.

In my previous article we have discussed what is TDE, how it works, its pros and cons. In this article I’m going to cover how to implement transparent data encryption to your server. It’s very simple to implement TDE, below are the steps that needs to be completed to enable TDE.

- Create or obtain a certificate protected by the master key
- Create a database encryption key and protect it by the certificate
- Set the database to use encryption
