tarcisio-marinho/GonnaCry — reverse-engineered prompt

Build me a safe learning version of this Linux ransomware project so I can understand how it works without hurting any real computer.

I want a Python app that only runs inside a clearly marked demo folder it creates itself. It should make sample files, encrypt only those sample files, show a fake ransom style warning for education, then let me decrypt everything back. Please include the basic crypto flow from the README, like AES 256 CBC for file contents, a random key and IV for each file, and RSA 2048 wrapping of keys, but keep it harmless and easy to reset.

Also add a tiny local web server or mock server to show how key exchange would work, plus clear warnings in the app and README that it must never touch real user files. Don’t add spreading, persistence, database killing, wallpaper changing, or anything that would make it usable as real malware. Look up current docs online if you need to.
