This weekend, CTFZone 2023 was running, and after solving a few of the easier challenges, I ended up spending all of my time on the last crypto question, ‘Wise sage’, which I managed to blood ~6 hours before the end of the CTF.

This week, the wonderful HackTM CTF was up and running, and I tried my best at the various crypto tasks available. In this post, I’ll go over the first two that I managed to solve, they were a ton of fun and I had the opportunity of learning a lot, so once again thanks y011d4 for writing really cool challenges.
