这个程序很不错，根据用户电脑的硬件（硬盘）序列号生成唯一软件注册码，不用再怕你的软件被破解发愁了。并可以对注册码进行二次加工，比如将生成的注册码按字母倒排、顺排互换、数字交换、分离和变形等，最终形成正式的注册码。-This procedure is very good, according to a user' s computer hardware (hard drive) the only software to generate a serial number registration key, no longer afraid of you worried about how the software was cracked.
