Sample SQL 2005 Encryption Code

by  mrdenny  Posted    (Edited  )
This is based off of the CTP edition of SQL 2005.
This sample code will create a encryption key, open the key, and use the key to encrypt some data, then decrypt the data, then close the key.
Code: 
OPEN SYMMETRIC KEY PrivateData DECRYPTION  BY PASSWORD ='Password'

CREATE TABLE UserData
(Data VARBINARY(255))

DECLARE @Key_GUID UNIQUEIDENTIFIER

SELECT @Key_GUID = Key_GUID
FROM sys.symmetric_keys
WHERE Name = 'PrivateData'
INSERT INTO UserData
(Data)
VALUES
(EncryptByKey(@Key_Guid, 'RawData', 1))

SELECT Data
FROM UserData

SELECT CONVERT(VARCHAR(20), DecryptByKey(UserData.Data, 1)) AS Data
FROM UserData

DROP TABLE UserData

CLOSE SYMMETRIC KEY PrivateData
