用C语言简单的实现了DES三重加密以及解密算法功能。- C language to achieve the encryption and decryption of information.

本代码使用C#语言实现了RSA和DES算法，其中通过分段处理的方式解决了RSA对较大数据的加解密。(This code block implements the algorithm of RSA & DES,and we resolved the encryption and decryption of data with large size on RSA by segmental processing.)

DES分组密码算法的C语言实现，包含头文件和.c主文件(DES block cipher algorithm)
