Description

😊 I'm learning 🧠 how to make my own HTTP server in C! 🗺️ Here's my cool little journal 📖 website; try looking up flag 🚩! It doesn't work 💔 in some browsers, though. 🙇

---

Flag format: sdctf{...}

To connect, click the "Create" button. Install wsrx, then connect to the wss:// URL. If you're using the CLI, the output will have something like,

Hi, I am not RX, RX is here -> 127.0.0.1:<PORT>

That's wsrx's wacky way of saying you can open http://127.0.0.1:<PORT>/ in your browser.

Hints

Sorry for not clarifying this earlier 🙏, but making a few hundred 💯💯💯💯 requests in series 🚶 isn't considered fuzzing 👌 by our rules 📜 (I was told this should be obvious 🙄). That may be necessary for this challenge 🎮 because my friend 💃 says my server is a bit ⚠️nondeterministic⚠️! 😵‍💫

Deployment

$ make build
