基于VB的EXE文件注册加密与防非法复制的思考及实现

Thinking and realization of VB-based EXE file's registering encryption and anti-piracy

在分析常见应用程序加密方法的基础上,阐述了基于VB开发环境实现身份确定、密钥生成的算法与过程,重点探讨用CPU号及网卡物理地址实现EXE文件注册加密、防非法复制功能的算法.实验表明,该方法加密的EXE程序不影响原EXE程序的正常运行,且其只能安装在合法用户的电脑上.

Based on the analysis of common application program＇s encryption methods, the paper expatiated on the algorithm and process of ID identified and key creating in VB development environment, especially, discussed the algorithm and realization of executable file＇s registering encryption with CPU number and NIC physical address, and the function of anti-piracy, and it can only run in legal clients＇ computers.
