![]() If we query the sys.certificates table we can see that the Certificate is already encrypted with Master Key SELECT name,pvt_key_encryption_type_desc FROM sys.certificates where = 'TDECertificate' –Create a Master Key and this will reside inside Master Database USE ĬREATE MASTER KEY ENCRYPTION BY a Certificate and protect it with Master Key USE ĬREATE CERTIFICATE TDECertificate WITH SUBJECT = 'SQL SRVR TDE Certificate' I decided to go with this pattern where I will first create a Master Key followed by creating a certificate which will be protected by the Master Key.Create a Database Encryption Key and protect it with the certificate and then turn on encryption for the database. Note – TDE has performance overheads,hence proper testing is required before its implemented to production environments.Ī detailed explanation of TDE can be found under this Microsoft Article. This blog post deals with TDE on SQL Server 2012. ![]() I was interested to test TDE in Denali to understand if there are any major changes for encryption,and with the release of SQL Server 2012 RC 0 I decided to do this testing. TDE was introduced in SQL Server 2008 as an Enterprise/Developer edition feature.This feature allows to encrypt the whole database and includes database backup’s.
