基于MD5的软件注册码的设计与实现

摘要

In this paper, first we summarise several common software register codes at present, analyse the principle and characteristics of the register code, then design and implement a new register code. This one is based on MD5, uses hard disk type and serial number as computer's fingerprint information, and takes the XOR operation of disk' s serial number as additional information. The new code plays a certain role on software protection.%在阐述目前几种常用的注册方式的基础上,分析注册码的原理和特点,设计并实现一种基于MD5的,以硬盘型号+序列号为计算机指纹信息.以磁盘序列号进行异或运算为附加信息的注册码,它对保护软件起到一定的作用.
