ASP.NET2.0中配置文件的加密与解密

首先添加引用: using System.Web.Configuration;

加密操作如下:
Private Sub ProtectSection(ByVal sectionName As String, ByVal provider As String)
Configuration config =
WebConfigurationManager.
OpenWebConfiguration(Request.ApplicationPath)

Dim section As ConfigurationSection = config.GetSection(sectionName)

If section <> Nothing And Not section.SectionInformation.IsProtected Then
section.SectionInformation.ProtectSection(provider)
config.Save()
End If
End Sub

解密操作如下:
Private Sub UnProtectSection(ByVal sectionName As String)
Configuration config =
WebConfigurationManager.
OpenWebConfiguration(Request.ApplicationPath)

Dim section As ConfigurationSection = config.GetSection(sectionName)

If section <> Nothing And section.SectionInformation.IsProtected Then
section.SectionInformation.UnprotectSection()
config.Save()
End If
End Sub

实践:
加密前的配置文件:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="name" value="shy520" />
<add key="address" value="cnblogs" />
</appSettings>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

加密后的配置文件:
<?xml version="1.0"?>
<configuration>
<appSettings configProtectionProvider="DataProtectionConfigurationProvider">
<EncryptedData>
<CipherData>
<CipherValue>

    ASP.NET 2.0 中有一个新的安全特性.可以对 Web.config 文件中的任何配置节进行加密处理，可以通过手工运行工具aspnet_regiis或者编程来完成这个工作。如果你可以直接访问你的Web 服务器，你可以通过运行如下的命令行：

     cd  %windows%\Microsoft.NET\Framework\versionNumber

    aspnet_regiis -pe "connectionStrings" -app "/SampleApplication" –prov RsaProtectedConfigurationProvider

    只要web.config有写权限，加密就不是什么问题。。
