本文介绍如何使用 System.Web.Configuration 命名空间中的 WebConfigurationManager 类来实现 ASP.NET 应用中配置文件的加密与解密操作。通过示例代码展示了加密和解密的具体步骤，并给出了加密前后配置文件的内容对比。

首先添加引用: using System.Web.Configuration;

加密操作如下:

复制C#源代码

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:

复制C#源代码

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>AQAAANCMnd8BFdERjHoAwE/Cl+sBAAAABi1ATlNkEUGEf0XyWGL2XgQAAAACAAAAAAADZgAAqAAAABAAAABIhxMWlazAntwIIpST1CDXAAAAAASAAACgAAAAEAAAAPz/YKYx07cb+h4fqdr4fkLgAAAAX1Ieyc+WSxAfsDW1vn2C/fXsG2TAnYeUgaCov8e3nGFTHHsH91gLiqKregFPYzGRvW1xrez/3VwOmJI9eS7EFKrcXejNnHL66kg2iNRk3ntLNZlZtTs3cZ9w63u47VKAjs6miWsGBz2GntL/9UGHLELigrJcr3YJ+lsjOscExQnvHGvA48EfxpD+tEiFBtgXeHsFkQXcqGySshx16vCt2GUNUC3ZmEAhBhUsAFkPIYqelYHd4+m9a/xPe2tqwGIbla1wbW2NDEfrzJPwnkfmpNqRhXijKImipwXbDVYy6o0UAAAAs8DsuYNOhJ7qAjJa2c/4eUC7sks=

        </EncryptedData>
    </appSettings>
    <system.web>
        <compilation debug="true"/>
    </system.web>
</configuration>
