破坏托管变量的内容 [英] Trashing the content of managed variables

问题描述

我有一个使用加密技术的应用程序，主要是在流（文件和内存）中，我根据需要将其解密到新的MemoryStream中。所有这一切都运行良好。
唯一的问题是，当我完成它时，我想要删除MemoryStream的内容（以及字符串等我将部分复制到其中）以防止它以解密的形式被分页到磁盘通过交换文件。
在老式的C ++中，我会在删除它之前用随机垃圾突击显示数据 - 管理对象有什么办法吗？

解决方案

Hi
您可以在安全内存流上使用Clear（）方法。

Yours Farhad。

I have an application using cryptography, mostly in streams (file and memory) which I decrypt as needed into a new MemoryStream. All this works well.
Only thing is, I would like to trash the content of the MemoryStream when I am done with it (as well as strings etc I copy portions into) to prevent it ever getting paged to disk in decrypted form via the swap file.
In "good old fashioned" C++ I would just blitz the data with random rubbish before I deleted it - is there any way with managed objects?

解决方案

See here[^]

Hi You can use Clear() Method on secure memory stream to do is.
Yours Farhad.
