DES

一个中国剩余定理的简单算法,密码学基础算法(Chinese Remainder Theorem a simple algorithm, based on cryptography algorithm)

说明：  密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)

说明：  vb 加密解密程序 动态加密使用非常方便...(vb encryption and decryption process is very convenient to use dynamic 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.)

RSA加密算法，实现对文字的加密，将文字转化成数字后用RSA原理进行加密(This is RSA encryption algorithm)

3des加密解密,des加密解密该算法通过编译，可以直接使用。(3DES encryption and decryption algorithms.)

VMp——一款可以超强保护文件防止破解的加壳工具，软件设计员的绝佳伴侣！ (VMp- a super-protected files can be packed to prevent cracking of the tools, software designers the perfect partner!)

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）(a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1))

VC编写的简单DES加密程序，密钥由用户手动输入，可加密字符串(VC prepared by the simple DES encryption program, the key to manually input by the user)
