(对Web.config文件加密)encrypting sensitive information stored in the web.config file

为了系统安全，需要对数据库的连接字符串进行加密：

1.引入Configuration名称空间 ：


using System.Web.Configuration;

2.加密代码如下：


protected void EncryptConfig(bool bEncrypt)




...{


string path = "/SMTWeb";


Configuration config = WebConfigurationManager.OpenWebConfiguration(path);


ConfigurationSection appSettings = config.GetSection("connectionStrings");


if (bEncrypt)




...{


appSettings.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");


}


else




...{


appSettings.SectionInformation.UnprotectSection();


}


config.Save();


}
