Pick your tool
Hands-on security, the fun way.
A set of interactive cybersecurity tools, have fun!
Enigma Machine
A working replica of the WWII cipher device. Choose rotors, rings, and plugboard, then encrypt or decode a secret message.
The Password Game
Build a password that satisfies a gloriously ridiculous policy. Every rule you meet unlocks a harder one. Don't forget your security token!
Steganography Tool
Hide a secret message inside an ordinary image, or reveal one that's already there. The picture looks completely normal.
Password Strength Checker
See how long your password would take to crack, and why length beats complexity. Runs entirely in your browser.
QR Code Decoder
Drop in a QR image to see where it goes — before you scan it. Spot anything funny, avoid "quishing" scams. Does not check for redirects.
Metadata Scrubber
See what a photo quietly reveals — GPS location, device information, timestamps — then scrub it clean, or plant decoy metadata of your own.
