关于ECC椭圆曲线加密算法在软件注册中的应用(The ECC Paper about software Registration)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

用C/C++实现加解密算法及其应用：DES（或AES）和基于DES（或AES）的CMAC。(With C/C++ achieve encryption and decryption algorithm and its application: DES (or AES) and based on DES (or AES) of CMAC.)

自己动手写加壳程序，按照文档一步一步来，做你自己的加壳程序！(Packers to write himself, according to the document step by step, do your own packers!)

基于miracl大数库的椭圆曲线EC的验证签名算法的c语言实现(Based on large numbers miracl library EC verification of an elliptic curve signature algorithm c-language implementation)

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

该程序使用C++写的一个基于递归子程序算法的语法翻译器，是在vs2012环境下编写的，供大家参考和学习(The program uses C++ to write an algorithm based on recursive subroutine syntax interpreter is written in vs2012 environment, for your reference and learning)

我自己编写的rsa算法，实现了加密和解密功能

VMPC加密解密算法。已对x86优化，其他平台也可用。(VMPC encryption and decryption algorithms. Has been optimized for x86, other platforms are also available.)

一种加密算法,可以直接对密文进行操作，而不需要知道相应的明文。(homomorphic encryption)
