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.
This is explained further in the diagram below. 1  Server sends a copy of its asymmetric public key. 2  Browser creates a symmetric session key and encrypts it with the server's asymmetric public key. 3  Server decrypts the encrypted session key using its asymmetric private key to get the symmetric session key.
