Great job at showing what the thought process is when starting with reverse engineering code.

This is simple but very clever

One should note that XOR is a perfectly (as in absolutely) secure method of encryption as long as the key is used only once. This means that the key should be at least the length of the plaintext, which doesn't happen here, allowing for a third way to solve this.

Explaining with hands is an art form in itself :) love your work John, keep it up!

It's not that difficult !! It's like 1. (a and b gives you c) 2.(b and c gives you a ) 3. (a and c gives you b )

All are related to each other in an x_or function of python

I mean we can all tear down on people who are trying to help or we could realise there are others that don't know as much as us and realise it wasn't ment for us. I learnt something from this even as insignificant as it was. But yeah you know everything so let it rip....

Great job. I just changed == to != then anything you enter as a password works.

I'm glad you could actually do a bit more than making the file an executable on this reverse engineering challenge 😅

This made me think about utilitarianutilitarianutilitarian I wonder what is the algorithm to find how long a word is before it starts repeating, if you didn’t know the word to begin with
