本代码实现了playfair加密方法的变种，手动输入一个密钥和一串需要加密的字符串，解密的时候，则输入密钥和已加密的字符串，即加密解密是一个程序。详细请看代码。(This code implements a variant of the playfair encryption method to manually enter a key and a string of encrypted string decryption, enter the key and the encrypted string, that is, encryption decryption is a program. Look at the code in detail.)

说明：  DES的加密和解密。在VC++6.0下运行。(Des encryption and decryption)

说明：  AES加密的matlab程序，把关键步骤的函数都提供了，主要是英文教材上的源码(AES encrypted matlab program)

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. )

DES加密详细文档，有源码。。。值得一下阿-DES encryption detailed documentation, source code. . . Worth about A

AES加密算法，包括轮密钥的产生、加密和解密。全部在一个文件，容易阅读。(AES encryption algorithm, including round keys generation, and encryption and decryption. All in a file, easy to read. )

DES加密算法的Visual C++实现-DES encryption algorithm Visual C++ Realize

加密算法RSA，DSA等，用C++实现，内附加有详细的说明(Encryption algorithm RSA, DSA, etc., using C++ Realize, with additional detail has)
