DES-complete

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)

说明：  使用维吉尼亚密码进行控制台编程，实现对英文文本文件的加解密！(Virginia password using the console program, to achieve the English version of the document encryption and decryption!)

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

加密文件夹,十分好用 使用visual basic环境编程(lock file)

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:)

椭圆曲线密码算法及其应用论文，对椭圆曲线加解密算法实现具有很好参考价值(Elliptic curve cryptography algorithm and its application papers, the elliptic curve encryption and decryption algorithm to achieve a good reference value )

ElGamal加密算法，经过测试可以编译运行(ElGamal Encryption )

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)
