HackingLab是一处不错的CTF训练平台，题目主要是WEB方向，从易到难，适合刷题训练。

0x01 key在哪里？

过关地址

右键查看源码就可以看到key。

<!--key is jflsjklejflkdsjfklds-->

0x02 再加密一次你就得到key啦~

加密之后的数据为xrlvf23xfqwsxsqf

密文再加密一次得到明文，应该是rot-13加密，随便找个在线解密网站，得到key。

keyis23ksdjfkfds

0x03 猜猜这是经过了多少次加密？

加密后的字符串为：

0x04 据说MD5加密很安全，真的是么？

e0960851294d7b2253978ba858e24633

直接cmd5就可以了。

bighp

0x05 种族歧视

小明同学今天访问了一个网站，竟然不允许中国人访问！太坑了，于是小明同学决心一定要进去一探究竟！
通关地址

burp抓包，唯一和foreigner有关的应该就是language了吧，改一下Accept-Language，拿到key。

key is: *(TU687jksf6&*

0x06 HAHA浏览器

据说信息安全小组最近出了一款新的浏览器，叫HAHA浏览器，有些题目必须通过HAHA浏览器才能答对。小明同学坚决不要装HAHA浏览器，怕有后门，但是如何才能过这个需要安装HAHA浏览器才能过的题目呢？
通关地址

看着题目就知道是改ua了，直接抓包，改ua为HAHA，拿到key。

恭喜您，成功安装HAHA浏览器！key is: meiyouHAHAliulanqi

0x07 key究竟在哪里呢？

上一次小明同学轻松找到了key，感觉这么简单的题目多无聊，于是有了找key的加强版，那么key这次会藏在哪里呢？
通关地址

key在request headers里。

Key:kjh%#$#%FDjjj

0x08 key又找不到了

小明这次可真找不到key去哪里了，你能帮他找到key吗？
通关地址

点到这里找key的链接，跳转了一下，抓包看看，记得截断返回包，在302跳转的时候出现了key的地址。

<a href="./key_is_here_now_.php">___</a><!--都告诉了到这里找key的啦-->

拿到key。

key: ohHTTP302dd

0x09 冒充登陆用户

小明来到一个网站，还是想要key，但是却怎么逗登陆不了，你能帮他登陆吗？
通关地址

request headers里有一处Set-Cookie:Login=0，用edit this cookie改成Login=1就好了。

key is: yescookieedit7823789KJ

0x0A 比较数字大小

只要比服务器上的数字大就可以了！
通关地址

浏览器的地方限制了位数，抓包改掉就好了。

key is 768HKyu678567&*&K

0x0B 本地的诱惑

小明扫描了他心爱的小红的电脑，发现开放了一个80端口，但是当小明去访问的时候却发现只允许从本地访问，可他心爱的小红不敢让这个诡异的小明触碰她的电脑，可小明真的想知道小红电脑的80端口到底隐藏着什么秘密(key)？
通关地址

headers里添加X-Forwarded-For: 127.0.0.1就行了。

key is ^&*(UIHKJjkadshf

0x0C 就不让你访问

小明设计了一个网站，因为总是遭受黑客攻击后台，所以这次他把后台放到了一个无论是什么人都找不到的地方....可最后还是被黑客找到了，并被放置了一个黑页，写到:find you ,no more than 3 secs!
通关地址

看看常用的后台地址，都404了，试试robots.txt，发现有。

访问那个路径，看到：

试试login.php，拿到key。
