+
+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"
+
+<img src="https://imgur.com/Cqov6VD.png"/>
+
+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)
+```

+We got the flag !!!
