不错的希尔代码，希尔是一种经典的加密算法，加密可以通过一线形变换，脱密再做依次逆变换。密钥就是变换矩阵本身。-good code Hill, Hill is a classic encryption algorithms, encryption can transform line shape, followed again from close inverse transform. Key is the transformation matrix itself.

3重DES算法是加密标准的过渡算法，现阶段在各个加密领域仍有较广泛的应用，本文件用c语言实现了3重DES的加密算法，包含了加解密过程的所有算法，对学习信息安全的人员有较好的参考价值！

DES加密算法的实现和演示，具体算法见网上，程序中有注释-DES encryption algorithm and demonstrate the achievement of the specific algorithm see online, proceedings have Notes

The class has a methode named make_CRC that gets a byte stream and start/end offsets then calculate and return a 16 bit CRC according to determined POLYNAMIAL.The POLYNAMIAL is a private field of the class.
