简单的流量分析

为了共同的利益，【组织1】和【组织2】成立了联盟，并遵守共同约定的协议。为了让协议的制定和修改更加公
平，组织1和组织2共同决定：当三位以上【组织1】成员和三位以上【组织2】成员同意时，才可以制定或修改协
议。为了实现这一功能，联盟的印章被锁在密码保险柜中，而保险柜的密码只通过Shamir秘密分享方案分享给【组织
1】和【组织2】的每一位成员。
现在，【组织1】的【成员1】、【成员2】、【成员4】，【组织2】的【成员3】、【成员4】、【成员5】一致同
意制定新的协议。请还原出这套方案的设计思路，按照这套方案的思路恢复出保险柜密码，取出印章吧！

黑盒破解II-时间谜题
去年大家已经破解掉了黑盒子系统，现在飞船的发动机引擎已经可以启动了，但常规的飞行速度是不能保证我们安全逃离的，速度与时间很重要!
该如何做呢？挑战一下吧。你可以输入一串精心构造的数据来触发超常规的引擎启动获得逃离，但别被他骗了，不过无论怎样，当你看到Flag时就已经成功了。

注：请运行在>= windows 7 x64 系统之上，程序正确输出格式：Flag:DDCTF{....}
