I think this problem shouldn’t be existed. Very poor quality
the concept itself is very interesting(I succeeded the breaking encrypting part)… but the encompassing things are just poor

How can we find these?
you can download the server.py file. the source code has the admin password, etc. i haven’t solved it yet- how do you connect to the challenge server?
i found a write-up from babafaba that works nicely as a tutorial- app_hackthebox_com challenges Not%20that%20random walkthroughs
(i’m still working on this challenge)
nonce = k; private key = x; there’s enough info to calculate these values. what makes it hard is that they are randomly chosen each time server.py is run.
k=random.randint(k_min, k_max) & x=random.randint(1, q-1) where q is an extremely large number but is a public parameter.
i haven’t solved this yet, i can’t seem to get k & x to converge on useful values.

Feel free to dm me for any doubts. It was quite hard for me
