Hey everyone — thanks for checking this out. I built this because running CTF events usually means stitching together scripts, manual flag hashing, and one-off writeups. I wanted a single place where you can spin up a stego, crypto, RSA, forensic, or RE challenge in seconds and get everything an organizer needs: the challenge file, the full decode path, hints you can drip to players, and a SHA-256 hash for verification. What’s live now (5 generators): Generator Highlights Stego 34 steps, LSB + spectrogram + containers Crypto 39 ciphers, crib drag, hash crack, key reuse RSA 20 attack types from Wiener to padding oracle Forensic Polyglot, PCAP, metadata, NTFS, firmware RE Obfuscation, logic gates, XOR chain, ELF via Docker
