你需要先搞一个openssl的库,然后调用相应的md5的函数就好了

找不到md5.h的头文件 将你的md5.h头文件跟你的c文件放在同一目录下

1. md5.h: #pragma once typedef unsigned long int UINT32; typedef unsigned short int UINT16; /× MD5 context. */ typedef struct { UINT32 state[4]; /× state (ABCD) */ UINT32 count[2]; /× number of bits, modulo 2^64 (lsb first) *...

1、主要就是调用库函数,MD5加密说到底也是函数计算,没有什么思路的问题,了解md5的发明算法,本质是一个数学问题。 2、例程: #ifndef MD5_H#define MD5_H typedef struct{ unsigned int count[2]; unsigned int state[4]; unsigned char buff...

相关库函数如下: #include unsigned char *MD5(const unsigned char *d, unsigned long n,unsigned char *md); int MD5_Init(MD5_CTX *c); int MD5_Update(MD5_CTX *c, const void *data,unsigned long len); int MD5_Final(unsigned char *md,...
