ASP.NET2.0中配置文件的加密与解密

 2006-06-26 17:11:26 来源:WEB开发网   
核心提示: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 = WebConfigurationManag

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>
   <CipherValue>
