主要是对注册机的简单的开发以及应用，包括注册机的如何操作。(Mainly on the development of RI and simple applications, including RI' s how.)

Hideseek可将秘密文件隐写到指定图片中，并可检测隐写信息，本文是对该软件的使用说明。(hide &seek to run the file through individual test run normally. Hidden secret documents can be written to the specified picture, and can detect steganographic message.)

删除系统某存储区中的证书， 代码参考msdn(removal system of a storage area of the certificate, a code reference VARIANT)

MD5VB2010实现MD5加密，计算机VB程序(MD5VB2010 achieve MD5 encryption, computer VB program)

VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

用C/C++实现加解密算法及其应用：AES 和基于AES 的CMAC(Encryption and decryption algorithm and its application with C/C++: AES and CMAC based on AES)

rsa 实现代码，运用大数算法#include "afx.h" #include "Integer.h" #include <string> #include <iostream> using namespace std //构造大数对象并初始化为零 CInteger::CInteger() { m_nLength=1 for(int i=0 i<BI_MAXLEN i++)m_ulValue[i]=0 } //解构大数对象 CInteger::~CInteger() { } /*大数比较 调用方式：N.Cmp(A) 返回值：若N<A返回-1；若N=A返回0；若N>A返回1 */ int CInteger::Cmp(CInteger& A)(#include "afx.h" #include "Integer.h" #include <string> #include <iostream> using namespace std //构造大数对象并初始化为零 CInteger::CInteger() { m_nLength=1 for(int i=0 i<BI_MAXLEN i++)m_ulValue[i]=0 } //解构大数对象 CInteger::~CInteger() { } /*大数比较 调用方式：N.Cmp(A) 返回值：若N<A返回-1；若N=A返回0；若N>A返回1 */ int CInteger::Cmp(CInteger& A))

SHA-256源代码，三个对外的函数：void SHA256Init (SHA256Context *sc) void SHA256Update (SHA256Context *sc, const void *data, uint32_t len) void SHA256Final (SHA256Context *sc, uint8_t hash[SHA256_HASH_SIZE]) 第一个函数初始化，第二个函数输入要hash的字符串，第三个函数输出结果(SHA-256 source code, three external function: void SHA256Init (SHA256Context* sc) void SHA256Update (SHA256Context* sc, const void* data, uint32_t len) void SHA256Final (SHA256Context* sc, uint8_t hash [SHA256_HASH_SIZE]) The first function is initialized, the second hash function, enter the string, the third function of output)

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)

说明：  信息安全相关，经典加密算法A5，通过编译(Information security-related, classic encryption algorithm A5, through compiler)
