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)

说明：  获取硬盘物理序列号,用来对软件加密，vs2008工程。(HD number)

FlexNet Publisher Licensing Toolkit 11.9.1 Installation Guide

基于VB的M5数学密码算法源码,有需要的就下载吧。(VB-based M5 mathematical algorithm source code, there is a need to download it.)

可以对文件进行加解密，这是自己编写的实验作业(Can encrypt and decrypt files, it is their job to prepare experimental)

这两个工程主要用CSP 1、CSPTEST 写的比较乱 主要是给当时一个朋友做参考调用的 完成非对称密钥的生成、导入、导出、加密、解密、对称的加密解密、签名、验证。 2、CSTTEST2 写的比前个好些，但是平时上班，下班自己也要写论文，所以花的时间也不太多，很多地方都偷懒了。比如文件大小我没有用NEW 而且指定了1024 有需要的朋友可以自己修改。这个工程主要是非对称的密钥的导出和导入，还有就是会话密钥的操作。(these two works mainly with a CSP. CSPTEST comparison was made mainly to the chaos when a friend called to refer to the completion of the non-symmetric key generation, importing and exporting, encryption, decryption, symmetric encryption and decryption, signature, the certification. 2, CSTTEST2 write better than in the previous months, but usually go to work and finish their own toilet paper so I spent the time is not too much, all of the lazy. For instance, file size I have not used the NEW 1024 and designated a need to amend their friends. The project mainly non-symmetric keys to the Export and Import, there is the session key operation.)

这是一个小程序,凯撒解密,自己写的,以后还会扩展的(This is a simple program for a example of ceasar cipher. It is produced by myself and I want to extend it to a substitution cipher program in some days.)

DES加密的雪崩效应分析，按照作业要求做的。(DES encryption of the avalanche effect analysis, done in accordance with operational requirements.)

基于crypto++实现RSA密钥对生成，密钥长度1024，vs2010实现(generate RSA key pair based on Crypto++，and save the key pairs which is 1024 bit in txt file )

仿射密码体制加解密，较移位代换等加解密体制，更加优越。(Affine cipher encryption and decryption, a shift substitution and encryption and decryption system, more superior.)
