MD5算法的实现。MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。 -MD5 algorithm. MD5 to 512 groups to deal with the importation of information and each group was also divided into 16 groups of 32 seats, After a series of processing, the output from the algorithm 4 32 subgroups, 4 32 this group will generate a cascade 128 hash value.

现在很多J2EE应用都采用一个license文件来授权系统的使用，特别是在系统购买的早期，会提供有限制的license文件对系统进行限制，比如试用版有譬如IP、日期、最大用户数量的限制等。 而License文件中的Base64或BEA公司现在是WebLo

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.
