DD_PassWord

快速取模指数算法，C++编写，下载即可编译运行，RSA算法里面需要用到的(Take the fast modular exponentiation algorithm, C++ to prepare, you can compile and run the download, the RSA algorithm which need)

密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)

说明：  用visual c++ 写的des加密算法演示 (with visual c write des encryption algorithm demo)

VC编写的简单DES加密程序，密钥由用户手动输入，可加密字符串(VC prepared by the simple DES encryption program, the key to manually input by the user)

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)

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 )

国密算法sm实现 sm2数字签名 密钥交换，sm3，sm4，已实现、求sm2第四部分公钥加密c实现源码。。。江湖救急。。。(sm2，sm3，sm4。。。)

一个袖珍的vc++加密软件，同时还可以解密，加密文件的范围挺大的，几乎所有文件都可以加密，输入密码并解密，好像不是真正意义的加密，只不过是用文件额外加密的方法进行加密，较早时候的程序，不过编译还是顺利的。 (A pocket-sized vc++ encryption software, but also can decrypt encrypted files the scope of getting bigger, almost all the files can be encrypted, enter the password and decrypt the encryption does not seem real, but the file is an additional method of encryption to encrypt Earlier procedures, but the compiler is still smooth.)

通过MATLAB的编程，实现对图片的加密，奇异值的分解，离散变化，程序简单，明了。(Through MATLAB programming, realize the image encryption, singular value decomposition and discrete changes, procedure is simple, clear.)

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)
