Solution for Natas web security wargame with by XORing the plaintext with the ciphertext...

Currently I am playing some wargames on overthewire.org.

The first 10 levels were very easy and everyone with some technical knowledge and programming experience should be able to solve them. But somehow I got stuck for a few hours on level 11. The task is to modify a XOR encrypted cookie. For some reason I couldn't figure out how to obtain the xor key that was used.

The challenge was to reverse engineer the key …

  • From another program over the API (programming approach)

and furthermore there are 3 very different modes GoogleScraper …

Depth First Search and Breadth First Search

I am right in front of a ton of exams and I need to learn about algorithms and data structures. When I read about pseudocode of Graph traversal algorithms, I thought:
Why not actually implement them in a real programming language? So I did so and now you can study my code now here. I guess this problem was solved a thousand times before, but I learnt something and I hope my approach has some uniqueness to it.

Additionlay, you can also generate …
