药品进销存管理系统算法的详细分析
【破解作者】 jsliyangsj
【作者邮箱】 sjcrack@yahoo.com.cn
【使用工具】 peid OllyDbg1.10
【破解平台】 Winxp
【软件名称】 药品进销存管理系统
【软件地址】 http://www.onlinedown.net/soft/37048.htm
软件是用VB编写的
我的机器码:701098763
我的输入码:12345678
因为是VB,下断点:_Vbastrcmp,_Vbastrcomp,发现没用,改用_VbaVartsteq

发现注册码已经在那里了,明码比较,但我们当然要分析算法的,注册是次要的,
再次输入,想找出关键的CALL计算注册码的地方就是找不到!
而且发现,当一断在00643A80时,用d 00161844(不一定是这个,反复CTRL+F2后固定)注册码已经的躺在那里了
二却也进不到原程序领空。还发现当“取消”注册对话框CTRL+F2后时再查看,就没有了,干脆,就在 00161844
下内存写入断点(此时,应该是CTRL+F2后的第一次也就是说d 00161844并没有发现注册码)

总结算法:
一共分为3次计算,取第一次计算结果的前2位,取第二次计算的全部,取第三次计算的
前4位,三次组合即为注册码:
第一次:将机器码转化为16进制与38E338E39相乘,取后8位进行SAR1运算,运算的结果加上
自己的2进制的最高位,然后把此次计算得到的结果转化为10进制,取前2位。
第二次:将机器码转化为16进制与30C30C31相乘,取后8位进行SAR2运算,运算的结果加上
自己的2进制的最高位,得到的结果与28B200B7相加,将结果转化为10进制,取其全部
第三次:机器码本身与9相乘,直接取前4位,
