Legislative Bills. Legislation begins with the submission of a bill to the legislature for consideration. A bill is a draft, or tentative version, of what might become part of the written law.
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.
An example of a symmetric algorithm is DES. Asymmetric ciphers (also called public-key cryptography) make a public key universally available, while only one individual possesses the private key. When data is encrypted with the public key, it can only be decrypted with the private key, and vice versa.
