2016年3月4日に開催されたBoston Key Party CTFにチームm1z0r3として少しだけ参加した.大会からかなり日が経ってしまって今更感があるが,今回はbob's hatというRSA暗号の問題のWrite-upを書こうと思う. http://bostonkey.party/ bob's hat - Crypto 4 問題概要 Task: bob’s hat — 4 : crypto : Alice and Bob are close together, likely because they have a lot of things in common.This is why Alice asked him a small *q*uestion, about something cooler than a wiener.
