CryptoHack is a fun platform to learn modern cryptography through solving challenges and cracking insecure code. Can you reach the top of the leaderboard?

It was founded by two crypto enthusiasts from the UK, hyperreality and Jack. hyperreality is currently working as a devops engineer and Jack is studying for a PhD in black holes.

We bonded over our shared passion for solving crypto CTF challenges, but realised that most people find it a tough topic. We wanted to build a "HackTheBox of crypto", where users are encouraged to learn about how crypto works, and how to break it when it doesn't. We'll be continuing to release new challenges to stay up-to-date with the latest attacks and techniques.

The site was released to the world on 26th March 2020.

Yes, I totally agree with you. It is very rare such a site. I remind that I'm not a coder (it remains a dream-job), and I can tell that I learned a lot in just few challenges.
Great site!!!
