【问题描述】:
在我的配置文件中,我有一些敏感信息我想加密以提高安全性。
这是我的代码(按预期工作):
class Program
{
static void Main(string[] args)
{
System.Configuration.ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
fileMap.ExeConfigFilename = @"D:\Web_S\Prep\test\test.exe.config";
System.Configuration.Configuration configuration = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
string userNameWithoutEncryption = configuration.AppSettings.Settings["username"].Value;
EncryptAppSettings("appSettings", configuration);
}
protected static void EncryptAppSettings(string section, Configuration configuration)
{
AppSettingsSection objAppsettings = (AppSettingsSection)configuration.GetSection(section);
objAppsettings.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");
objAppsettings.SectionInformation.ForceSave = true;
configuration.Save(ConfigurationSaveMode.Modified);
}
}
.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="username" value="a2zmenu"/>
<add key="password" value="password"/>
</appSettings>
</configuration>
加密后的 .config 如下所示:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="customAppSettings" type="System.Configuration.NameValueSectionHandler" />
</configSections>
<appSettings configProtectionProvider="RsaProtectedConfigurationProvider">
<EncryptedData Type="http://www.w3.org/2001/04/xmlenc#Element"

</CipherData>
</EncryptedData>
</appSettings>
</configuration>
我有以下问题: 让
等信息安全吗 <EncryptedKey xmlns="http://www.w3.org/2001/04/xmlenc#">
<EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-1_5" />
在 .config 中?
难道不能用这些信息解密吗? 文件加密后,你能确认我可以评论这一行吗:
EncryptAppSettings("appSettings", configuration);
当我尝试在使用此行加密文件后获取用户名值时:
string userNameafterEncryption = configuration.AppSettings.Settings["username"].Value;
即使我的文件现在已加密,我也会得到解密的值。我不明白为什么...
感谢您的帮助
