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

超级兔子有一个文件加密功能，文件被加密以后，打开该文件时，回转到控制面板，可是我们忘了密码怎么办呢？这里提供了一个简单方法-Super rabbit has a file encryption, file is encrypted then, open the file, back to the control panel, but we forget the password how to do? Here provides a simple way

采用Arnold变换对彩色图像进行加密操作，并能实现解密，恢复原图像(Adopt Arnold transform pairs of color image carry on encryption operation, and can realize decryption, restore the the original image)

CRC在软件加密中的应用_1.rar 不知道这里有没，传个看看(CRC in software encryption application _1.rar do not know if there are not, pass a look)

摩斯密码 加密 解密 说明以衣VB源代码(Morse code By VBasic6.0)

这是一个加密算法,我自己也看不懂,发上来大家看一下-This is an encryption algorithm, I, for one can not read, the U.S. authorities to look at

公钥密码基础设施应用技术体系 密码设备应用接口规范 做系统安全性的参考文档。(Application of public key cryptography infrastructure equipment application technology system password security system interface specifications make reference to the document.)

 What is EAQUAL?     The intention of EAQUAL is to provide a objective quality measure for coded/ decoded audio      files. Currently the code is based on the ITU-R recommendation BS.1387.      EAQUAL will not supersede listening tests, but can be a useful tool to support listening tests,      categorize different coding algorithms and find bugs in algorithms. The more input files are      taken for the analysis, the better the results of EAQUAL will fit the reality.

题目：某个公司采用公用电话传递数据，数据是四位的整数，在传递过程中是加密的，加密规则如下： 　　　 每位数字都加上5,然后用和除以10的余数代替该数字，再将第一位和第四位交换，第二位和第三位交换。 1.程序分析： 2.程序源代码：(Topic: a company USES the public telephone relay data, data is four integers, in the relay in the process is encrypted, encryption rules are as follows: Each Numbers add 5, then use and divided by the number of 10 instead of a remnant, then the first and fourth exchange, the second and third exchange. 1. The program analysis: 2. The source code:)
