如何在Windows中的Rsync算法中生成哈希码 [英] How to generate the Hash code in Rsync Algorithm in windows

问题描述

我学会了Rsync算法(7stpes).
但是如何使用Windows c ++为一个文件生成哈希码.

i learned the Rsync Algorithm (7stpes).
but how to generate the hash code for the one file using windows c++.

推荐答案

Go to rsync official site...

http://rsync.samba.org 下载源代码，并且在checksum.c中有一个函数...

http://rsync.samba.org download the source code and in checksum.c there is a function...

void file_checksum(char *fname, char *sum, OFF_T size)

which actually computes checksum and md4 hash for a file. You need to port few functions like opening file and shared memory. use CreateFileMapping, MapViewOfFile, UnMapViewOfFile instead.If you don't want to write all that you can download my CSharedMemory from here...
