问题描述：

Can you encrypt fast enough?

初始页面，不管怎么样点击Submit都会显示"Too slow!"

依据Html源码，编写Python脚本进行利用

import requests
import hashlib
import re

url="http://docker.hackthebox.eu:34650/"

r=requests.session()
out=r.get(url)

rr = re.compile(r"<h3 align='center'>(S+)</h3>", re.I)
str1 = rr.findall(out.text)
str2=hashlib.md5(str1[0].encode('utf-8')).hexdigest()

data={'hash': str2}
out = r.post(url = url, data = data)

print(out.text)

Run result

<html>
<head>
<title>emdee five for life</title>
</head>
<body style="background-color:powderblue;">
<h1 align='center'>MD5 encrypt this string</h1><h3 align='center'>JBUxqcV4rWsw17043rxv</h3><p align='center'>HTB{N1c3_ScrIpt1nG_B0i!}</p><center><form action="" method="post">
<input type="text" name="hash" placeholder="MD5" align='center'></input>
</br>
<input type="submit" value="Submit"></input>
</form></center>
</body>
</html>
