数据库数据加密和解密

MVC的演习的一起,将要进入其他一个等级了,将增多会员功能。在登前面,一些备工作要开的。一步一个脚印吧。设计会员功能,其中密码字段,Insus.NET想对其进行加密。就盖之加密,还得花费上部分时间来整治。
Insus.NET参考MSDN网站,列有数据库加密解密例子(以下是在SQL Server
2012进行):

--创建数据库主密钥
CREATE MASTER KEY ENCRYPTION BY PASSWORD ='Pass#Tutorial#word'
GO

 

--创建证书
CREATE CERTIFICATE PasswordCert 
with SUBJECT = 'Member Password Certificate'
GO

 

--创建非对称密钥
CREATE ASYMMETRIC KEY PasswordAsymmetric
    WITH ALGORITHM = RSA_2048 --{ RSA_512 | RSA_1024 | RSA_2048 } 
    ENCRYPTION BY PASSWORD = 'Pass#Tutorial#word'; 
GO

 

--创建对称密钥
CREATE SYMMETRIC KEY PasswordSymmetric
    WITH ALGORITHM = AES_256 --{ AES_128 | AES_192 | AES_256 | TRIPLE_DES_3KEY }
    ENCRYPTION BY PASSWORD = 'Pass#Tutorial#word';
GO

 

--由证书加密对称密钥
CREATE SYMMETRIC KEY SymmetricByCert
    WITH ALGORITHM = AES_256
    ENCRYPTION BY CERTIFICATE PasswordCert;
GO

 

--由对称密钥加密对称密钥
OPEN SYMMETRIC KEY PasswordSymmetric
    DECRYPTION BY PASSWORD='Pass#Tutorial#word'

CREATE SYMMETRIC KEY SymmetricBySy
    WITH ALGORITHM = AES_256
    ENCRYPTION BY SYMMETRIC KEY PasswordSymmetric;
GO

 

--由非对称密钥加密对称密钥
CREATE SYMMETRIC KEY SymmetricByAsy
    WITH ALGORITHM = AES_256
    ENCRYPTION BY ASYMMETRIC KEY PasswordAsymmetric;
GO

 

创之后,会要对应的数据库之下,显示如下:
