FileEncrypt

本程序是仿射密码的加密与解密，用C语言编写的，经测试没有问题(This procedure is affine password encryption and decryption, written in C, tested no problem)

一些常用的方法，很不错的实例，可以拿来学习，很不错哟-Some commonly used method, it is a good example, can be used to study, very good yo

its about new technque using stream cipher

一个用BCB写的壳！-with BCB was a shell!

内容:基于jdk1.4的加密算法的具体实现，算法包括MD5,SHA-1,DES,DESede,RSA等-: jdk1.4 based on the encryption algorithm to realize the algorithm including MD5, SHA-1, DES, DESede, RSA, etc.

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

1、 实验要求：用高级语言实现IDEA算法的加密-1, the experimental requirements: use of high-level language implementation of the IDEA encryption algorithm
