神秘小笔记
#1.二维码
之所以写这个，是因为之前做题看见二维码，就用手机直接扫，直接被学长狠狠的拷打了，所以之后我就改掉这个习惯用了QR。
但是，在二维码这上面，还是有很多知识是我不知道的，这边点名批评京华杯签到题，不会ps，压根不会做。
今天这个笔记，主要是记录一个新的题目，CTFSHOW菜狗杯的迅疾响应，这一题给我整傻了，还是看了wp才懂。
这道题的附件是一张二维码，扫不出来，虽然有隐藏文件，那只是调侃flag不在这。
这边要引入一个新的工具 ，叫QRazyBox。
二维码编辑器，你看它就能扫出来信息。

这边用这个就能得到一半的flag了，那么另一半呢，我们需要编辑二维码。
这个工具能纠错我们错误的二维码， 我虽然没有按照纠错涂白完，但已经有另一半了。

是一个很有用的工具，相信以后也会用到的。
#2.Hackber
Hackber,一个在做web题很好用的工具，传参，post，改cookie啊，等等，有了这个工具，我就不要再傻乎乎的搁那curl这，curl -X那的了，我曾经两次下载它，第一次载入谷歌失败，第二次即便装了也不会用，本以为就此失败，没想到偶然间，竟得到了高人指点，大师，我悟了，话不多说，开始我的故事。
事情的起因是这题，我依稀还记得这是我刚开始接触web做过的题，当时的我是个fw，根本没用头绪，而现在我有头绪了，但还是个fw，也是刚才才做出来的。
打开 题目，显示方式不对，这边就是get方式不行，要改为post。
hackbor工具一招搞定，马上就看到题目源码了，之前还是傻乎乎的curl -X POST 呢，
题目要求一个Cookie: flag=1 然后传参web=like ,最后一个POST CNSS=join
我真是服我自己了，怎么这么简单的题都卡。
吐槽之余也是收获了一个好工具的用法，唉。
