[Write-up] picoCTF 2018 賽期內有解開的題目總覽


今年期待很久的 picoCTF 2018在台灣時間9/29 0:00 到 10/13 01:00結束
為期兩個禮拜的賽期
自己也趁這個競賽期間逼自己多學一些

「志在學,不在名次」
說是這樣說,也是希望能有個好名次就是了

未提供相片說明。
這次我的得分是 8135分,名次落在第 1031名
而前幾名的得分是 35135分,破台就是這個分數了吧

然而這次也是單打獨鬥
好多東西沒辦法跟人討論,多了一份孤獨感阿 (Q __ Q)

總而言之,底下是我在賽期內解開的題目
很多都會有蠻多廢話的
畢竟是紀錄當時的思考
還請多多包涵

而之後也會慢慢把還沒解開的題目
趁有時間解一解,參考別人的作法
會再慢慢補上

P.s 如果有興趣的各位,歡迎去玩玩看
picoCTF的優點是題目是無時無刻開放的,註冊一下就能玩了
假設有人來看這個網誌的話 :D
