/* 带密钥的md5算法库md5lib.h共有下列函数：



　　char* MDString (char *)

输入任意一个字符串，经过md5算法处理后，返回结果：一个定长（32个字符）字符串



　　char* MDFile (char *)

　　输入任意一个文件名，文件内容经过md5算法处理后，返回结果：一个定长（32个字符）字符串



　　char* hmac_md5(char* text, char* key)

　　输入任意一个字符串text,和一个用做密钥的字符串key,经过hmac_md5算法处理，返回处理结果：一个定长字符串（32个字符）



　　具体使用方法可参考例子sample.c,其运行结果在本文后面。

　　

　　注意在调用时需要添加头文件 #include "md5lib.h"
