C ++：如何在编译时加密字符串？ [英] C++: How to encrypt strings at compile time?

问题描述

我想在我的.exe中隐藏一些字符串，所以人们不能只是打开.exe，看看所有的字符串。我不在乎加密方法的强度，所以我可能会使用XOR等。

I want to hide some strings in my .exe so people can't simply just open the .exe and look at all the strings there. I don't care about the strength of the encrypting method, so I will probably use XOR etc.

如何在编译时这样做？这样我的字符串不会存储在.exe，但加密的版本。

How can I do this at compile time? That way my strings won't be stored in the .exe but the encrypted versions would. Then, I would just use my decrypting function every time to display those strings on screen.

推荐答案

你可以使用宏或者加密来加密这些字符串。写自己的预处理器

you can encrypt it using macros or write your own preprocessor

#define CRYPT8(str) { CRYPT8_(str "\0\0\0\0\0\0\0\0") }
#define CRYPT8_(str) (str)[0] + 1, (str)[1] + 2, (str)[2] + 3, (str)[3] + 4, (str)[4] + 5, (str)[5] + 6, (str)[6] + 7, (str)[7] + 8, '\0'

// calling it
const char str[] = CRYPT8("ntdll");
