加密配置节点

 1 Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/");
 2
 3            ConnectionStringsSection connectSection = (ConnectionStringsSection)config.ConnectionStrings;
 4
 5            if (connectSection != null)
 6            {
 7                if (connectSection.SectionInformation.IsProtected)
 8                {
 9                    connectSection.SectionInformation.UnprotectSection();
10                }
11                else
12                {
13                    connectSection.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
14
15                }
16
17                config.Save();
18            }

效果：

 

  <connectionStrings configProtectionProvider="DataProtectionConfigurationProvider">

从页面获取该加密节点时。会自动解密，返回普通文本。

还可以用命令行加密码

aspnet_regiis -pe "要加密的节点名" -app "Web应用程序的虚拟路径" -prov "加密提供程序的名称" 

 

并不是所有的设置都可以被加密的，有些运行在ASP。NET之外的，例如<httpRuntime>节点，通常是由IIS Web服务使用的。
