ASP.NET2.0中配置文件的加密与解密

2008-12-09 14:43 369 查看

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>
