We are presented with this html page having a string and told to encrpyt it with MD5 but when we try to submit it after encrpyting we get a message "Too Slow"
|
||
|
|

Intercepting the request with `Burp Suite` and found that we have to make a POST request to send the MD5 hash
|

Also the string is generated randomly so we need to script it and the best language for this is python so I used python libraries `requests` , `hashlib` and `BeautifulSoup`
|
||
|
|
|
||
|
|
```python
|
||
|
|
import hashlib
|
||
|
|
import requests
|
||
|
|
from bs4 import BeautifulSoup
|
||
|
|
|
||
|
|
# Persists cookies across all requests
|
||
|
|
request = requests.session()
|
||
|
|
# URL For the challenge page
|
||
|
|
url = "http://159.65.25.97:31667"
|
||
|
|
page = request.get(url)
|
||
|
|
|
||
|
|
soup = BeautifulSoup(page.content,"html.parser")
|
||
|
|
# Saving the string to be encrpyted
|
||
|
|
string_to_encrpyt = soup.select('h3')[0].text
|
||
|
|
|
||
|
|
# Caluclating hash of the string
|
||
|
|
MD5 = hashlib.md5(string_to_encrpyt.encode('utf-8')).hexdigest()
|
||
|
|
|
||
|
|
# POST data to send
|
||
|
|
data = {'hash' :MD5}
|
||
|
|
|
||
|
|
# Sending data as POST request
|
||
|
|
response = request.post(url,data)
|
||
|
|
print(response.text)
|
||
|
|
```
