A Cryptex is a special container which has mechanical combination lock (rotating rings with letters or digits), which people used hundreds years ago to keep secrets. Inside the cylinder there’s a container, where you can keep piece of paper with secret data.
Today it’s better to use a USB flash drive for data storage.
This Cryptex USB flash drive was engineered in the accordance with original sketches of Leonardo Da Vinci.
Mechanical combination lock protect your digital data. You need to know 5-digit code to get access to the USB flash drive hidden inside. The only one, who has the password can use it. A great way not only to protect the information, but also to add an element of a game into everyday life.
It even comes in this sick packaging, which I think just really makes it seem more like something you'd find in da vinci's workshop than the design itself.
