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">
