CryptoHack – A fun free platform for learning cryptography (cryptohack.org)

Awesome! This reminds me of https://cryptopals.com/

Greetings

I'd love something like this for complete noobs like me. I can't even crack the registration code. Any suggestions for resources? Cryptopals?

Hey there. I read this as "a fun-free platform" and was very confused for a bit. You might want to reconsider the order of your adjectives.
