本人花了一个月时间，试图找出某私服的数据包加密方式（该私服在官方的基础上自己做了改进），最终找到如下关键处，不知道下面的数据是如何生成的，或者说，跟格雷码是否有关系？请高手指教，谢谢。
1.经过分析，025170D8 -025174C8  这1024个字节，是第一个表，数据是这样取的
      AND EAX,0FFh  ；该指令将eax的高位置0，保留低字节
      MOV EAX,DWORD PTR DS:[EAX*4+25170D8h] ；将低字节*4对应的4个字节存eax
大家知道，一个字节表示的十进制数在0~255之间，而表一刚好256个Dword（1024/4），刚好一一对应

2.025174D8 -025178C8 这1024个字节，是第二个表，取数据过程与1相同

3.仔细观察可以发现，第一个表和第二个表并不是孤立的，在地址空间上，他们是连续的，在数据上也有关联，如
025170D8  C6 63 63 A5   F8 7C 7C 84
025174D8  63 00 00 00   7C 00 00 00

4.在跟踪过程中发现如下字符串 “2,5,2,1,6,8,9,3,4,1,8,4,2,0”；该串有可能跟这两个表有关系，但是本人不敢肯定

问题描述完毕，谢谢大家。
