Crackme 29

首先用OD查找字符串

首先看到了比较跳转的地方，我输入的name:1234567 serial:123456

开始找算法
1.处理name的

2.处理serial的

编写exploit

name = raw_input("name:")name = 'A' + names = ''f = ''cx = 0x0afor i in range (1,len(name)):    s += chr(i^ord(name[i]))for i in range (0,len(s)):    f += chr(cx^ord(s[i]))    cx += 1print f
