DESEncryptionDecrypt
编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data.

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))

该文件能用Visual C++6.0打开编译实现加密解密功能，并能通过少量的修改改(修改处程序源码中已标明)镶嵌到其他的程序源码中实现加密解密功能。 可直接使用。
(The file can use Visual C++6.0 to open compiled encryption and decryption functions through a few modifications reform (modify at program source code has been marked) inlaid into the other program source code to achieve encryption and decryption functions. Can be used directly.)

Hash_sha256
sha256计算代码，非常好用的代码，大家可以用这个代码直接计算哈希值，sha256实现
依次执行
SHA256Init、
SHA256Update
SHA256Final
三个函数即可得到sha256结果(sha256 sourse code，Is very usefull)

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
*/
