SQL Server 2005: using symmetric keys to encrypt data. In SQL Server 2005, the recommended method for encrypting data is to use symmetric keys. A symmetric key can be created using the CREATE SYMMETRIC KEY statement. Information about symmetric keys is stored in the sys.symmetric_keys catalog.
Asymmetric keys use one password to encrypt data (called the public key) and another to decrypt data (called the private key). SQL Server has two primary applications for keys: a service master key (SMK) generated on and for a SQL Server instance, and a database master key (DMK) used for a database.
