Help & Rules

0. You are allowed to share flags.

1. Bruteforce is for noobs.

2. I don't care if you cheat.

You can try to break it, but honestly I don't think that it's even possible :p It might be easier to just complete the challenge normally.

4. There's no logging in possibility. That's because for the moment I can't afford a vps and github pages only support static pages

5. If you want to contact me about something (That might be job proposition or you want to add some cool challenges. You can do that by writing to me at: 4rlenrey@gmail.com)

6. If it changes color to white that means that you've solved the challenge.
