点击一次 - 如何加密连接字符串 [英] Click-Once - How to encrypt connection strings

问题描述

我有一个WPF应用程序，连接字符串存储在App.config中。在单次点击部署中加密这些连接字符串的最佳方式是什么？

谢谢

解决方案

如果这是一个将配置的connectionString并且通过应用程序的实例在单个计算机（不共享多台计算机）上使用，您可以使用DPAPI（Data Protection API）的.NET托管包装器 - ProtectedData类（System.Security.Cryptography）。

你还可以使用一个整洁的技巧（你应该决定使用这个类）是为字符串编码和解码创建扩展方法，所以操作变得简单：

  string encodedString = myConnectionString.EncodeString（）; 
 
 string decodedString = encodedString.DecodeString（）; 
  

希望这有帮助！

I have a WPF application with connections strings stored in the App.config. What is the best way of encrypting these connection strings in a click-once deployment?

Thanks

解决方案

If this is a connectionString that will be configured and used on a single computer (not shared across multiple computers) by an instance of your application, you can use the .NET managed wrapper of the DPAPI (Data Protection API) - the ProtectedData class (System.Security.Cryptography).

A neat trick you could also use (should you decide to use this class) is to create extension methods for Encoding and Decoding a string, so the operations become as simple as:

string encodedString = myConnectionString.EncodeString();

string decodedString = encodedString.DecodeString();

Hope this helps!
