如何在win控制台应用程序中读取加密的app.config appSettings？
如何在win控制台应用程序中读取加密的app.config appSettings？
提问于 2014-11-23 18:08:27
编辑:这个问题没有任何意义。我把.vshost.config和exe.config混在一起了。该如何处理这些内容？
Program.cs main：
databaseName = System.Configuration.ConfigurationManager.AppSettings["DatabaseName"];
databaseUser = System.Configuration.ConfigurationManager.AppSettings["DatabaseUser"];
databasePwd = System.Configuration.ConfigurationManager.AppSettings["DatabasePassword"];
port = System.Configuration.ConfigurationManager.AppSettings["Port"];
logDirectory = System.Configuration.ConfigurationManager.AppSettings["LogDirectory"];
strLogLevel = System.Configuration.ConfigurationManager.AppSettings["LogLevel"];
EncryptConfigSection("appSettings");这是我加密文件的方式：
private static void EncryptConfigSection(string sectionKey)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ConfigurationSection section = config.GetSection(sectionKey);
if (section != null)
{
if (!section.SectionInformation.IsProtected)
{
if (!section.ElementInformation.IsLocked)
{
section.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
section.SectionInformation.ForceSave = true;
config.Save(ConfigurationSaveMode.Full);
}
}
}
}文件被复制和加密，就像我在web上找到的示例一样：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings configProtectionProvider="DataProtectionConfigurationProvider">
<EncryptedData>
<CipherData>
<CipherValue>AQAAANCMnd8BFdERjHoAwE/Cl+sBAAAAvsQ9Wtc58EC5EZCEq91EogQAAAACAAAAAAADZgAAwAAAABAAAClVHhpR5xAw4KFNyrANtavAAAAAASAAACgAAAAEAAAABHkhg2ztiY3bdWhTG9iy6twAAAAF5mAHt7oDQWCgc1iLL2hYUJZgmquU8XsojjqXVQdV1CaW3XEBXBDhN30DEZizP3F5rGGMCjL9CVjHfsPAfvVYyRHCcup22BoByb5y/MDujaASpaWZYcdxSxLijT/Zq3zB8hiWyWPruY0G7emYEOq/xQAAADkgStCMABwo3oZx/VXHD41wrsjXg==</CipherValue>
</CipherData>
</EncryptedData>
</appSettings>
</configuration>但是下一次我开始的时候，我就看不懂了。所有读取的值都为空。我很自然地从文件夹中删除了原始的未加密文件。

您可以将KeyValueConfigurationCollection用于appSettings密钥，将ConnectionStringSettingsCollection用于connectionStrings密钥。
这在未加密时进行加密，在加密时解密并打印值：
private static void CryptConfig (string[] sectionKeys)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
foreach (string sectionKey in sectionKeys)
{
ConfigurationSection section = config.GetSection(sectionKey);
if (section != null)
{
if (section.ElementInformation.IsLocked)
{
Console.WriteLine("Section: {0} is locked", sectionKey);
}
else
{
if (!section.SectionInformation.IsProtected)
{
//%windir%\system32\Microsoft\Protect\S-1-5-18
section.SectionInformation.ProtectSection(DPCP);
section.SectionInformation.ForceSave = true;
Console.WriteLine("Encrypting: {0} {1}", section.SectionInformation.Name, section.SectionInformation.SectionName);
}
else
{ // display values for current config application name value pairs
foreach (KeyValueConfigurationElement x in config.AppSettings.Settings)
{
Console.WriteLine("Key: {0} Value:{1}", x.Key, x.Value);
}
foreach (ConnectionStringSettings x in config.ConnectionStrings.ConnectionStrings)
{
Console.WriteLine("Name: {0} Provider:{1} Cs:{2}", x.Name, x.ProviderName, x.ConnectionString);
}
//
section.SectionInformation.UnprotectSection();
section.SectionInformation.ForceSave = true;
Console.WriteLine("Decrypting: {0} {1}", section.SectionInformation.Name, section.SectionInformation.SectionName);
}
}
}
else
{
Console.WriteLine("Section: {0} is null", sectionKey);
}
}
//
config.Save(ConfigurationSaveMode.Full);
Console.WriteLine("Saving file: {0}", config.FilePath);
}使用的App.config：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="DatabaseName" value="databaseName"/>
<add key="DatabaseUser" value="databaseUser"/>
<add key="DatabasePassword" value="databasePwd"/>
<add key="Port" value="port"/>
<add key="LogDirectory" value="logDirectory"/>
<add key="LogLevel" value="strLogLevel"/>
</appSettings>
<connectionStrings>
<add name="SecurePassDataBase" connectionString="Data Source=D-xxxx;Initial Catalog=DEMO;User ID=sa;Password=******" />
</connectionStrings>
</configuration>Stack Overflow用户

下面是一个非常简单的代码，您可以使用它
RsaProtectedConfigurationProvider Sample
做了一些小的修改。
static public void ProtectSection()
{
// Get the current configuration file.
System.Configuration.Configuration config =
ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.None);
// Get the section.
ConfigurationSection section = config.GetSection("appSettings");
// Protect (encrypt)the section.
section.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");
// Save the encrypted section.
section.SectionInformation.ForceSave = true;
config.Save(ConfigurationSaveMode.Full);
// Display decrypted configuration
// section. Note, the system
// uses the Rsa provider to decrypt
// the section transparently.
string sectionXml = section.SectionInformation.GetRawXml();
Console.WriteLine("Decrypted section:");
Console.WriteLine(sectionXml);

试试这个&你会得到你想要的：
Console.WriteLine(ConfigurationManager.OpenExeConfiguration(Path.GetFileName(Assembly.GetExecutingAssembly().CodeBase).ToString()).FilePath.ToString());
string[] readText = File.ReadAllLines(ConfigurationManager.OpenExeConfiguration(Path.GetFileName(Assembly.GetExecutingAssembly().CodeBase).ToString()).FilePath.ToString());
foreach (string s in readText)
{
Console.WriteLine(s);
