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 void ProtectSection(string sectionName, string provider)


    {


        Configuration config =


            WebConfigurationManager.


                OpenWebConfiguration(Request.ApplicationPath);




        ConfigurationSection section = config.GetSection(sectionName);




        if (section != null && !section.SectionInformation.IsProtected)


        {


            section.SectionInformation.ProtectSection(provider);


            config.Save();


        }


    }

解密操作如下:


 private void UnProtectSection(string sectionName)


    {


        Configuration config =


            WebConfigurationManager.


                OpenWebConfiguration(Request.ApplicationPath);




        ConfigurationSection section = config.GetSection(sectionName);




        if (section != null && section.SectionInformation.IsProtected)


        {


            section.SectionInformation.UnprotectSection();


            config.Save();


        }


    }

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">
