Valiant, nothing is impossible.
Lock by lock and one after the other is the key. You cannot open door number 9 until you have unlocked number 8.

  • Very nice challenge I like this type of crypto, I've done little bruteforce in the end because something appeared 16 bytes far away of my calculation but in the end it's not so difficult just look at the encryption mode of operation

    Very nice and educational challenge
  • Cool challenge. Finally some modern crypto here. No brute force required - just understand the attack and flip away.

    Is it normal that the server does not respond? Nvm I looked for a web interface and didn't read the instructions... :-1:

    I just can't recreate what hex() does and how to do the decryption

  • Do we have to bruteforce this? Can anyone give me a nudge please?
