Symmetric Encryption

Abstract

Symmetric encryption is the class of encryption that involves using the same key (or two keys that are trivially related, mathematically speaking) for encryption and decryption. SQL Server provides support for symmetric encryption via a variety of algorithms, including AES, DES, Triple DES, RC2, and RC4. The SQL Server encryption hierarchy uses symmetric encryption algorithms to encrypt both keys and data. In this chapter, I’ll discuss how to create symmetric encryption keys and use symmetric encryption to secure your data and other encryption keys. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
