DES加密解密 通过制定的加密方法来加密(Encryption and decryption are encrypted by means of established encryption methods DES)

C++实现大整数类的运算符重载，输入输出重载，和关系判断重载(C++ achieve large integer class of operator overloading, overloading the input and output, and the relationship between judges overloaded)

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.)
