USE TestDB GO CREATE MASTER KEY ENCRYPTION BY PASSWORD = database master key is a symmetric key used to protect the private keys of certificates and asymmetric keys in the database. To create a Database Master Key, first, create the database "TestDB" in SQL Server and execute the following commands. In this article, we will discuss Database Master Key. TDE will not encrypt filestreams, remote BLOB stores.Before this article, I highly recommend reading Encrypt & Decrypt in SQL Server Part-1. TempDB is automatically encrypted when used with an encrypted database and remains encrypted until the session ends. The certificate can then be imported into a new database with the password where the DMK is used to re-encrypt the certificate upon storage. When a certificate is exported, it is decrypted and protected with The thumbprint in the record points to the certificate needed to decrypt the DEK. The DEK is stored in the database boot record for availability during recovery scenarios. The SMK is created during installation and stored in the master database. The Master Encryption Key (MEK) is protected with a mandatory password and 3DES.Ī copy of the MEK is encrypted using the Service Master Key ( SMK) and a copy is stored in the master database. The certificate, in turn, is stored in the master database and protected with another encryption layer using a database master key ( DMK). Certificates created by SQL Server have 1024 bit private keys. The encryption will be performed using a database encryption key ( DEK).
Transparent Data Encryption happens at the database-level – more specifically, I/O time encryption/decryption on all data and log files will be performed for the database under encryption.
