这是我的代码.

DROP SYMMETRIC KEY CL1AES256Key1;
GO
DROP CERTIFICATE CL1AES256Cert1
GO
DROP MASTER KEY
GO

USE MYDB
GO
IF NOT EXISTS 
(SELECT * FROM sys.symmetric_keys WHERE symmetric_key_id = 101)
CREATE MASTER KEY ENCRYPTION BY 
PASSWORD = '24RJFEGFJuifjei343'
GO

CREATE CERTIFICATE CL1AES256Cert1
   WITH SUBJECT = 'Encrypting certificate',
   EXPIRY_DATE = '12/31/2030';
GO

CREATE SYMMETRIC KEY CL1AES256Key1
    WITH ALGORITHM = AES_256
    ENCRYPTION BY CERTIFICATE CL1AES256Cert1;
GO

OPEN SYMMETRIC KEY CL1AES256Key1
DECRYPTION BY CERTIFICATE CL1AES256Cert1;
INSERT INTO TMP VALUES(ENCRYPTBYKEY(KEY_GUID('CL1AES256Key1'), 'Yummi'))
CLOSE SYMMETRIC KEY …
