Programmatically encrypting a config-file in .NET
提问by Seb Nilsson
Could somebody please do a rundown of how to programmatically encrypt a config-file in .NET, preferably in C#.
有人可以简要介绍一下如何以编程方式加密 .NET 中的配置文件，最好是在 C# 中。
What I would like to do is do some kind of check on an application's startup to see if a section is unprotected, and if it is, then encrypt it. This for both settings and connection-strings.
我想做的是对应用程序的启动进行某种检查，以查看某个部分是否不受保护，如果是，则对其进行加密。这适用于设置和连接字符串。
Also if anyone could list the types of encryption-providers and what is the difference between them.
此外，如果有人可以列出加密提供程序的类型以及它们之间的区别。
I don't know if the code for doing this in a normal WinForms-application is transparent to doing this in ASP.NET.
我不知道在普通 WinForms 应用程序中执行此操作的代码对于在 ASP.NET 中执行此操作是否透明。

There is a good article from 4 guys about Encrypting Configuration Information in ASP.NET 2.0 Applications
有 4 个人写了一篇关于在 ASP.NET 2.0 应用程序中加密配置信息的好文章
Hope this helps
希望这可以帮助

@TK: a hashing algo can only be 'guessed', not reverse engineered. One can only reconstruct the input to a hash value by completely guessing the input (apart from collisions, that is) This can be done by a rainbow crack for example (see an implementation of a rainbow cracker here)
@TK：散列算法只能“猜测”，不能逆向工程。人们只能通过完全猜测输入（除了冲突，即）将输入重建为哈希值，例如，这可以通过彩虹裂缝来完成（请参阅此处的彩虹裂缝实现）
I would say that a 3rd party encryption tool is not safer than the .NET framework encryption algorithms, these libraries just help you doing your job faster
我会说第 3 方加密工具并不比 .NET 框架加密算法更安全，这些库只是帮助您更快地完成工作

I haven't used it myself, but the Microsoft Enterprise library has good encryption support that will possibly suit your needs:
我自己没有使用过，但 Microsoft Enterprise 库具有良好的加密支持，可能会满足您的需求：
