asp.net2.0如何加密数据库联接字符串

在asp.net2.0中,发布网站时,加密web.config,这样可以有效保证数据库用户和密码安全,其步骤如下:

1.添加密钥

执行:C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_regiis -pc "hnlaw" -exp

其中"hnlaw"为密钥名称

2.添加web.config节点

在web.config的<configuration></configuration>之间添加:

<configProtectedData>

<providers>

<add keyContainerName="hnlaw" useMachineContainer="true" description="Uses RsaCryptoServiceProvider to encrypt and

decrypt" name="hnlaw" type="System.Configuration.RsaProtectedConfigurationProvider,System.Configuration, Version=2.0.0.0,

Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

</providers>

</configProtectedData>

注意:这里keyContainerName="hnlaw"和name="hnlaw"分别表示你的密钥名称;

3.加密web.config

到网站根目录添加一个批处理文件enweb.bat,内容如下:

@echo off

C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_regiis -pef "system.web/identity" "E:/HS Studio/Donet2/Hnlawyer" -prov

"hnlaw"

C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_regiis -pef "connectionStrings" "E:/HS Studio/Donet2/Hnlawyer" -prov

"hnlaw"

PAUSE

注册上面的的路径和名称!

运行后出现成功!

4.解密

同样到网站根目录添加一个批处理文件deweb.bat,内容如下:

@echo off

C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_regiis -pef "system.web/identity" "E:/HS Studio/Donet2/Hnlawyer"

C:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/aspnet_regiis -pdf "connectionStrings" "E:/HS Studio/Donet2/Hnlawyer"

PAUSE

最后就是要注意:做完后找到C:/Documents and Settings/All Users/Application Data/Microsoft/Crypto/RSA/MachineKeys目录下,找到生成

的密钥文件(可按时间查找),给上network service可读取权限,不然会出现Error message from the provider: The RSA key container could

not be opened.

无法读取

这样可能会出现,如果没有自己的服务器,没有权限修改MachineKeys目录,不知道还有其它解决办法,希望大家共享一下:)
