订单号：112233 注册码：036j5u499~f6242!深入分析
将程序载入x64dbg,进行调试分析 关键字搜索：F9运行程序,在所有模块中搜索关键字(简化分析流程) 注册码错误注册码正确双击进入，调试分析，看到注册流程，反向调试，逆转注册流程(输入错误的注册信息，使其注册成功，输入正确的注册信息，使其注册失败)

另一种效果，使其注册机制失效，不管输入的注册信息是否正确都显示注册成功跳转指令用nop填充 NOP 空操作
注册机编写
在关键判断上下断点，劫持注册流程，可以看到注册对比情况
EAX 01E0EA9C 11 为输入的注册码EDX 01E0B93C 036j5u499~f6242! 为程序计算出的正确的注册码思路编写程序提取出程序计算出的注册码
0051053E | E8 D546EFFF | call jzyq.404C18 |运行注册机，程序运行，点击注册，填写订单号，注册码，点击注册，注册机机输出正确的注册码
劫持补丁编写
劫持补丁劫持该地址并替换其原始指令程序，到达反注册机制效果，需下列信息已制作劫持补丁 被劫持地址信息
