【破解总结】1.用户名至少5位

2.name1=用户名右边3位+"csks[cscg]"+用户名左边3位+用户名得到新用户名

3.LenName1=新用户名长度

4.sum=累加上面的ascii值

5.str1=Sum转换成字符串，，由第3位决定取哪个字符:
   1：［
   2：中
   3：华
   4：软
   5：件
   6：解
   7：密
   8：同
   9：盟
   0：]

6.Sum1 = Sum xor 0x1980

7.A=Sum - LenName1

8.B=Sum1 - LenName1

9.C = A+B+LenName1

10.Sn = "csks" & B & Str1 & C & "[cscg]"

原帖由飘云
【破解工具】Peid0.94,OllyDbg,VB
...

一直对P-CODE比较仇视，在OD中调试让人想碰墙
老大没用VBExplorer和VKTDEBUG吗？

另外外界流传的飘云修改版QQ不知是否和PYG有关系，我在本论坛没有发现任何链接

老大出手的东东,就是不同凡响,P-CODE的,老大一个静态反编就搞定了,佩服!

看了一下，发现这个算法用Delphi写不如用易语言写来的简单（我刚开始学Delphi）

放了那么就，总算1个crackme被完整破解了。恭喜

我的crackme 0.2试过没有？？？

向老大学习.算法我还是不懂啊
