加密和解密ASP.NET配置文件(Web.config)

首先添加引用:usingSystemWebConfiguration;

加密操作如下:
PRivatevoidProtectSection(stringsectionNamestringprovider)
{
Configurationconfig=
WebConfigurationManager
OpenWebConfiguration(RequestapplicationPath);

ConfigurationSectionsection=configGetSection(sectionName);

if(section!=null&&!sectionSectionInformationIsProtected)
{
sectionSectionInformationProtectSection(provider);
configSave();
}
}

解密操作如下:
privatevoidUnProtectSection(stringsectionName)
{
Configurationconfig=
WebConfigurationManager
OpenWebConfiguration(RequestApplicationPath);

ConfigurationSectionsection=configGetSection(sectionName);

if(section!=null&&sectionSectionInformationIsProtected)
{
sectionSectionInformationUnprotectSection();
configSave();
}
}
实践:
加密前的配置文件:
<?xmlversion=""?>
<configuration>
<appSettings>
<addkey="name"value="shy"/>
<addkey="address"value="cnblogs"/>
</appSettings>
<systemweb>
<compilationdebug="true"/>
</systemweb>
</configuration>

加密后的配置文件(Webconfig):
<?xmlversion=""?>
<configuration>
<appSettingsconfigProtectionProvider="DataProtectionConfigurationProvider">
