RSA算法介绍-RSA algorithm introduced

DEC加密算法，信息安全类别，可以实现VC窗口验证的脚本。64位的明文输入块变为64位64位数据块按位重新组合，并把输出分为R0两部分，每部分各长

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.
