破解者

在生成注册码的时候使用了DES、RSA、MD5加密算法。由于这些算法都是公开的，为了迷惑破解者，需要对DES、RSA、MD5加密算法的输入输出数据进行变换处理。

DES , RSA , MD5 encrypt algorithms are used when producing registration number , Because these algorithms are all open , in order to puzzle cracker , the input and output data of these algorithms should be changed using some cryptographic transformation .

如果你把你的程序放在互联网上，特别是在共享软件发布站点，破解者将可能尝试破解他。

If you post your program on the Internet , especially at shareware distribution sites , crackers will probably attempt to attack it .

如果我们给出一个特殊的防护，破解者也将会找他们，因此这里我们将只是给出指引，提示，和建议。

If we gave specific defenses , crackers would be able to look for them as well , so we will just give guidelines , hints , and suggestions here .

但是目前基于虚拟机的软件保护技术并未对其自身的虚拟指令加以保护，破解者仍然可以通过分析虚拟指令破解虚拟机。

Software protection based on virtual machine technology has not its own virtual instruction protection , the crack will still be able to crack the virtual machine by analyzing the virtual instruction .
