我都已经下载，下载地址：

MD5 算法源码 c 写的-CSDN下载 https://download.csdn.net/download/happygrilclh/10869881

我使用的是输入是file string.

使用方法：

MD5Init是一个初始化函数，初始化核心变量，装入标准的幻数

MD5Update是MD5的主计算过程，inbuf是要变换的字节串，inputlen是长度，这个函数由getMD5ofStr调用，调用[之前][Link 1]需要调用md5init

MD5Final整理和填写输出结果.

The MD5Init(), MD5Update(), and MD5Final()	functions are the core func-
         tions.  Allocate an MD5_CTX, initialize it	with MD5Init(),	run over the
         data with MD5Update(), and	finally	extract	the result using MD5Final(),
         which will	also erase the MD5_CTX.
