说明：  rockey2是一种应用比较广泛且使用简单的加密锁。本程序适用于极域电子教室加密锁数据读取并记录成模拟狗所需的形式。稍加修改就能模拟rockey2加密锁了。本程序仅供研究适用，不得用于非法用途。
(rockey2 is a much wider application and use of simple encryption lock. This procedure applies to very domain lock encrypted electronic classrooms to read and record data into analog form of a dog required. A little modification will be able to lock the encryption rockey2 simulation. This procedure applies only for study, shall not be used for illegal purposes.)
