使用RsaProtectedConfigurationProvider加密/解密app.config部分 [英] Encryption / Decryption of app.config sections using RsaProtectedConfigurationProvider

问题描述

在安装我们的程序期间，我们运行此方法到app.config的encrpyt部分：

  //获取应用程序配置文件。 
配置config = 
 ConfigurationManager.OpenExeConfiguration（ConfigurationUserLevel.None）; 
 
 //定义Rsa提供程序名称。 
 const string provider =RsaProtectedConfigurationProvider; 
 
 //获取要保护的部分。 
 ConfigurationSection connStrings = config.ConnectionStrings; 
 
 if（connStrings！= null）
 {
 if（！connStrings.SectionInformation.IsProtected）
 {
 if（！connStrings.ElementInformation.IsLocked ）
 {
 //保护部分。 
 connStrings.SectionInformation.ProtectSection（provider）; 
 
 connStrings.SectionInformation.ForceSave = true; 
 config.Save（ConfigurationSaveMode.Full）; 
} 
} 
} 
  

但是如果我运行这个程序，我们遇到几个机器以下错误无法解密使用提供程序'RsaProtectedConfigurationProvider'。来自提供程序的错误消息：无法打开RSA密钥容器

当然，我搜索并找到此帮助，但这不工作。任何想法？

解决方案

在Win 7的Visual Studio 2010中调试时遇到类似的问题，UAC设置为默认保护。

为了解决这个问题，我不得不以管理员身份运行Visual Studio（以管理员身份运行）。

我有同样的问题，试图运行aspnet_regiis.exe加密我的web.config的部分。如果我没有运行命令行/控制台作为管理员，我会得到一个更加神秘的命令行错误：对象已经存在。

During the installation of our program we run this method to encrpyt sections of the app.config:

// Get the application configuration file.
Configuration config =
      ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

// Define the Rsa provider name.
const string provider = "RsaProtectedConfigurationProvider";

// Get the section to protect.
ConfigurationSection connStrings = config.ConnectionStrings;

if (connStrings != null)
{
    if (!connStrings.SectionInformation.IsProtected)
    {
        if (!connStrings.ElementInformation.IsLocked)
        {
            // Protect the section.
            connStrings.SectionInformation.ProtectSection(provider);

            connStrings.SectionInformation.ForceSave = true;
            config.Save(ConfigurationSaveMode.Full);
        }
    }
}

Works fine so far. But if I run this program, we encounter of several machines the following error "Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: The RSA key container could not be opened".

Of course I searched and found this help, but this doesn't work. Any ideas?

解决方案

I ran into similar issues while debugging within Visual Studio 2010 on Win 7 with UAC set to it's default protection.

In order for me to get around this issue, I had to run Visual Studio as the Administrator ("Run as Administrator").

I had the same issue with trying to run the aspnet_regiis.exe to encrypt the section of my web.config. If I didn't run the commandline/console "as Administrator" I would get a commandline error that was even more cryptic: "Object already exists."
