Luxor Net Key

A secret picture is your encryption key. Invented by Christian Rivera (DJ BrightFuture).

This whole demo runs in your browser. Nothing is uploaded. Your picture never leaves this page. Best key: a photo of your own random pencil drawing - unique, private, high-entropy.

1. Your secret message 2. Your secret picture (this is your key)

Locked envelope will appear here.

3. Unlock: pick the SAME picture file again

Your message will appear here if the picture matches.
