## Overview

Jay’s CTF Playground is an archive of nine cybersecurity challenges, not a single application. Its principal participant workflow is to obtain a challenge’s public artifact, investigate or exploit it, and recover a flag; the README describes public assets and intended solutions, while implementations vary by challenge. The graph preserves the documented crypto, forensics, and web branches, with extra detail for sampled web runtimes. Unexcerpted challenge internals are represented only at their existing directory paths; their internal flow is not inferred.

Main entry points: [`challanges/web/dark-side-of-asteroid/src/app.py`](https://github.com/jaysenlestari/ctf/blob/master/challanges/web/dark-side-of-asteroid/src/app.py) (Challenge App), [`challanges/crypto/baby-leaked`](https://github.com/jaysenlestari/ctf/tree/master/challanges/crypto/baby-leaked) (Baby Leaked), [`challanges/web/Cryptweb/src/app.py`](https://github.com/jaysenlestari/ctf/blob/master/challanges/web/Cryptweb/src/app.py) (Challenge App), [`challanges/web/Cryptweb/bot/bot.js`](https://github.com/jaysenlestari/ctf/blob/master/challanges/web/Cryptweb/bot/bot.js) (Admin Browser)
