1、 实验要求：用高级语言编写求自由距离的程序-1, the experimental requirements: high-level language used for the preparation of the procedures from the Freedom

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.

这是我的代码，我用 c 语言编写的库 gmp 结合时的代码。我在 Visual studio 2013 上进行编译。我的程序是计算值为公共密钥 n、 e、 秘密的关键 d 和后存储在文件的文本。该程序有 3 功能是计算，最后的工作会议，生成密钥并转到上一届会议。当用户选择退出程序的功能然后程序将退出。

MD5算法的ASP实现． 它在MD4的基础上增加了"安全-带子"（Safety-Belts）的概念。虽然MD5比MD4稍微慢一些，但却更为安全。MD5也为一种非常优秀的中间技术。-MD5 algorithm ASP. It MD4 increase on the basis of "safety-belt" (Safety-Belts) concept. Although MD5 than MD4 slightly slower, but more secure. MD5 also as a very good intermediate technology.
