rafidghanim/exploitarium — reverse-engineered prompt

Build me a local only cybersecurity practice workspace called Exploitarium. I want it to feel like a small training collection with four hands on labs, one for binary exploitation and pwn basics, one for reverse engineering and crackme style analysis, one for cryptanalysis and common crypto mistakes, and one for secure coding where you fix vulnerable code and run tests.

Keep everything clearly educational and safe. Use only synthetic programs, fake flags, fake data, and local services. Add simple docs for setup, methodology, contribution, and a roadmap so someone can clone it and start learning without guessing. Each lab should be runnable on its own with straightforward commands, and the secure coding one should support running tests for a specific challenge.

Please organize it so the labs live in one workspace and are easy to explore. If anything is unclear, check current docs online, but stay within the local training scope and do not add anything aimed at real world targets.
