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)

IBE基于身份的加密系统的系统叁数程序，使用VC6.0开发(IBE identity-based encryption system of systems Triple the number of procedures, the use of VC6.0 Development)

1、 所有密钥的装载与导出都采用密文方式； 2、 密钥管理系统采用3DES加密算法，采用根密钥生成系统、主密钥生成系统、初始化卡生成系统、密钥注入系统四级管理体制； 3、 在充分保证密钥安全的基础上，支持IC卡密钥的生成、注入、导出、备份、更新、服务等功能，实现密钥的安全管理； (1, the loading and export all keys are in cipher text 2, the key management system uses the 3DES encryption algorithm, using the root key generation system, the master key generation system, initialize the card generation system, key injection system four management systems 3, the key to ensure full security, based on the support of the IC card key generation, injection, export, backup, update, and service functions to achieve key security management )

看到RSA加密的C++类下载的人不少，我也下载了，并且稍微改动了一下，使它看上去更加易懂。在新年随手写了一套RSA文件加密，用win32dll封装使用了这个类，用C#写了文件加密和操作界面，可以实现密钥的保存和对任何文件的RSA加密操作。送给大家祝大家新年快乐。(see RSA encryption C downloaded to many people, I have downloaded and slightly altered a bit it looks more comprehensible. New Year threw in a written document RSA encryption, win32dll Compliant with the use of this category, C# to write document encryption and interface, can achieve key to the preservation of any documents and the RSA encryption operation. Give you wish you a happy New Year.)

加密程序的，实现了对代码的抽取乱序,区段加密和IAT的处理。 (Encryption procedures, the code of the extraction sequence, block encryption and IAT processing.)

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 )

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:)

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.)
