# CTFWriteUps

I will try organizing the challenges by difficulty and category in the README since some people are using them as practice, however the difficulty I give it may be different than what you would expect since I mainly do reverse engineering. I will try to keep difficulty consistent throughout each category though.

Some categories here will also not match what is on the challenge solution README, that is because here I will put into the actual category while there I just put what the ctf said it was.
