Description
This is not a real challenge, but rather an example of how to use Python to communicate with the remote services of FCSC, Hackropole, and more generally, with any service exposing a TCP port.
If you are not familiar with these concepts, start by installing the Python package pwntools on your machine.
This package is extremely useful in CTFs and helps simplify a lot of tasks.
In our case, we will only use it to communicate with a service exposing a TCP port.
Although it is possible to solve this challenge manually or directly from the provided template.py file, we recommend studying the different functions used in template.py.
These are the main functions used in pwntools for communicating with remote services, and they might be useful for you for FCSC or Hackropole challenges.
