加密二进制文件。 [英] Encrypting a binary file.

问题描述

是否可以使用C ++读取二进制文件，如.exe / .jpg文件，并使用一些简单的算法对其进行加密。



真正的问题是如何将整个.exe或jpg文件读入1维数组并进行操作。

Is it possible to read a binary file such as .exe / .jpg files using C++ and encrypt it using some simple algorithm.

The real question is how to read an entire .exe or jpg file into 1 dimensional array and manipulate it.

推荐答案

简单的答案是是。您可以加密任何类型的文件，而.exe / .dll只是另一种类型的文件。你必须要注意文件访问和所有权等明显的事情，但它可以毫无困难地完成。您通常无法写入当前正在使用的系统文件或文件。

The simple answer is "yes". You can encrypt any type of file, and a .exe/.dll is just another type of file. You have to beware of obvious things like file access and ownership but it can be done without significant trouble. You typically won''t be able to write to system files or files that are currently in use.
