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">
 <EncryptedData>
  <CipherData>
