Cryptographic Keys in SQL 2005

Certificates and Asymmetric keys (#updated June 2008)

Basics :
Both 'Certificates' and 'Asymmetric keys' use Asymmetric encryption (RSA keys).

Certificates (sql 2000+) allow importing of keys from certificate files.
Asymmetric keys (sql 2005+) support importing keys from strong name files or sql assemblies.

Certificate files (.CER) are created using Microsoft Cerfificate Services (Windows Server 2000, 2003) or Active Directory Certificate Services (Windows 2008)
