本文介绍如何使用 System.Web.Configuration 在 ASP.NET 应用中对 Web.config 文件的 appSettings 部分进行加密和解密操作，确保敏感信息的安全。

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>
