⚑ Mini-CTF

Four flags in the format OG{...} are hidden on this site. No special tools needed: a browser and some curiosity are enough.

Hints

1. #1

   What the browser receives is not only what it displays.

2. #2

   Developers talk to developers, in a place visitors rarely look.

3. #3

   Before the HTML even arrives, the server says things.

4. #4

   Some files tell robots where not to go. Humans, however, may go there.

Checking happens in your browser by comparing SHA-256 hashes: the flags are not in plain text in this page’s code.
