MD5SHA1

基本的DES加密算法，可以实现一些基本的功能，但是大型计算不适合(The basic DES encryption algorithm)

说明：  vb 加密解密程序 动态加密使用非常方便...(vb encryption and decryption process is very convenient to use dynamic encryption ...)

C++ implementation for S26

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. )

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 )

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)

程序采用当前最先进的Rijndael算法作为核心算法，带有可变块长和可变密钥长度的迭代块密码。块长和密钥长度可以分别指定成 128、192 或 256 位。多线程操作，保证加密时程序界面流畅，加密速度大约9M每秒。(Procedures using the most advanced as a core algorithm Rijndael algorithm with variable block length and variable key length of the iterative block password. Block length and key length can be specified as 128,192 or 256. Multi-threaded operation, to ensure smooth program interface encryption, encryption speed of about 9M per second.)

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