循环异或

有多种加密算法，如：字节取反、循环异或、码变换法、CSED、D3DES。-There are a variety of encryption algorithms, such as: anti-byte check, recycling XOR, code transformation, CSED, D3DES.

This software calculates the crc32 polynomial of a string. There is one class cCrc32.

素数生成算法，用于生成公共密钥，CA分配公共密钥。-prime number generation algorithm used to generate the public key, CA public key distribution.

自己做的一个数据加密的程序，程序简单，可以直接使用的。-Their own to do a data encryption procedures, the procedures simple, can be directly used.
