用C ++拆分文件 [英] Splitting a file in C++

问题描述

如何将包含整个文件（.exe / .jpg / .avi / .docx等）的数组拆分为2维矩阵（2d数组）的行。

这只是为了应用一些密码（加密）操作。

How to split an array containing an entire file (.exe/.jpg/.avi/.docx etc) into rows of a 2 dimensional matrix (2d array).
This is just to apply some cipher (encryption) operations.

推荐答案

您已经在加密二进制文件。 [ ^ ]。



但是，文件只是一个字节流，所以你只需将它读入一个字节数组然后根据你的内容操作内容要求。标准CRT库 fread function [ ^ ]，或Windows ReafFile函数 [ ^ ]，会做你想做的事。

You have already asked this question at Encrypting a binary file.[^].

However, a file is just a stream of bytes, so you just need to read it into a byte array and then manipulate the contents according to your requirements. The standard CRT library fread function[^], or the Windows ReafFile function[^], will do what you want.
