Twofish 采用128位数据块(128 bits lock)，128-192-256-bit 可变长度密钥。-using Twofish 128 blocks of data (128 bits lock) EliteConnect (TM) Universal-192-256-bit variable-length keys.

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。-Md5 algorithm with a key repository md5lib.h total of the following functions: char* MDString (char*) /* enter any one string, after md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* MDFile (char*) /* enter any of the file name, file contents through the md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* hmac_md5 (char* text, char* key) /* input a string of arbitrary text, and a string key used as key, after hmac_md5 algorithm processing, return processing results: a fixed-length string (32 characters)*/specific examples of the use of methods can be found sample.c, the results
