Windows上是否有某种安全的本地存储？ [英] Is there some sort of secure local storage on Windows?

问题描述

我正在想一个小工具。工具将会做什么并不重要。重要的是，该工具将需要在用户的HDD上存储一些敏感信息。 编辑：将存储的信息是用户的信息 - 我不是想保护我自己的内容，我通过该应用程序分发。

<我知道我需要加密这个信息。但那么，我在哪里可以安全地存储加密密码？这是一种无限递归...

那么，有没有办法加密Windows上的信息，并且安全地管理密码？当我说Windows时，我的意思是Windows XP SP2或更高版本。

我还应该注意，同一系统上的用户不能访问其他用户的信息（即使他们都在运行我的应用程序）。

我正在寻找这两个 - .NET 2.0（C＃）和本机（C / C ++）解决此问题的解决方案。 >

历史上，受保护的存储（XP中可用，只读）在vista +）：< a href =http://msdn.microsoft.com/en-us/library/bb432403%28VS.85%29.aspx =noreferrer> http://msdn.microsoft.com/en-us/图书馆/ bb432403％28VS.85％29.aspx

I was thinking of making a small tool. It is not important what the tool will do. The important thing, is that the tool will need to store some sensitive information on the user's HDD. EDIT: The information that will be stored is USER'S information - I'm not trying to protect my own content, that I distribute with the app.

I understand that I need to encrypt this information. But then, where do I safely store the encryption password? It's some sort of an infinite recursion...

So, is there a way, to encrypt information on windows, and have windows securely manage the passwords? When I say windows I mean Windows XP SP2 or later.

I should also note, that users on the same system must not have access to other users information (even when they are both running my application).

I'm looking for both - .NET 2.0 (C#) and native (C/C++) solutions to this problem.
