SQL CLR Cryptography
MICHAEL G. H. COLES, Rodney Landrum · Apress eBooks · 2009
Until this point, I’ve discussed the wide assortment of cryptographic functionality built in to SQL Server. The tools I’ve talked about include symmetric and asymmetric encryption functions, encryption key management, hashing, EKM, and TDE. These tools provide an impressive level of cryptographic functionality that can help make SQL Server databases more secure than ever.
