3重DES加密算法c语言实现

vc++6.0下的md5源程序-vc 6.0 source of md5

多数程序设计语言处理整数的能力是有限的，如C语言中，int类型数据范围是-32767----32767。实际问题的处理过程中往往涉及大整数的运算，如RSA加密算法要求至少64bit的整数，本程序是设计算法实现大整数的加减运算。-majority programming language processing is integral to the limited capacity, such as C language, int data type is the scope-32767---- 32767. Practical problems of the treatment process often involves large integer arithmetic, such as the RSA encryption algorithm requires at least 64-bit integers, the procedure is designed algorithm large integer addition and subtraction operations.

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.
