ASP.NET2.0中配置文件的加密与解密

2022-07-15 80酷酷网 80kuku.com

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

加密操作如下:

以下为引用的内容：

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:

以下为引用的内容：

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:

以下为引用的内容：
<?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>
