ASP.NET2.0中配置文件的加密与解密

ASP.NET2.0中配置文件的加密与解密

- flyinweb 2009-12-04 21:56:56



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">
