Longbottom's Locker got me extremely confused

Heya guys, been stuck on this one for a while, the worst part is that I’ve been looking in a rabbit hole and obviously found nothing.

Just realized I can look through some other files other than index and found something else that looks interesting. Python sorting seems like an option to reverse engineer the hashes or something, but I’m not sure.

I would really appreciate if anyone could give me some actual educational tips because I literally have no clue, not even an idea what to do next.

Hi, there is already another thread about this challenge. Have a look at it.
I’ve just solved it thanks to an initial hint of clarkkent (TY again!). Thanks to this challenge I’ve learnt a lot of new things, I find it very instructive. You can PM me for an hint

Thanks for the reply bro, I was just testing to see if my badge works, solved the challenge way back in 2018
