Mengenkripsi tabel database di SQL Server 2008

Anda memiliki opsi yang berbeda di sini.

• Anda dapat menggunakan enkripsi simetris untuk data Anda:

  BUAT TABEL penjualan (...)

Buat kunci simetris:

CREATE CERTIFICATE cert_sales WITH SUBJECT = N'Sales certificate',
START_DATE = N'2009-01-01', EXPIRY_DATE = N'2018-12-31';

CREATE SYMMETRIC KEY symkey_sales WITH ALGORITHM = AES_256 
ENCRYPTION BY CERTIFICATE cert_sales

Enkripsi data:

TRUNCATE TABLE sales;
OPEN SYMMETRIC KEY symkey_sales DECRYPTION BY CERTIFICATE cert_sales;
INSERT INTO sales() SELECT a, ENCRYPTBYKEY(Key_Guid(N'symkey_sales'), B) FROM T2;
CLOSE SYMMETRIC KEY symkey_sales;

Dekripsi data:

OPEN SYMMETRIC KEY symkey_sales DECRYPTION BY CERTIFICATE cert_sales;
SELECT a, CAST(DecryptByKey(B) as nvarchar(100)) FROM sales;
CLOSE SYMMETRIC KEY symkey_sales;

• Anda dapat menggunakan enkripsi asimetris untuk data Anda
• Anda dapat menggunakan Enkripsi Data Transparan untuk mengenkripsi semua file database:

Buat kunci master:

USE master
go
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'My$Strong$Password$123'

Buat sertifikat:

CREATE CERTIFICATE DEK_EncCert WITH SUBJECT = 'DEK Encryption Certificate'

Buat DEK:

USE MySecretDB
go
CREATE DATABASE ENCRYPTION KEY WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE DEK_EncCert

Aktifkan enkripsi:

ALTER DATABASE MySecretDB SET ENCRYPTION ON

• Anda dapat menggunakan BitLocker - enkripsi volume lengkap
