A Kickstarter project aims to give you a Bluetooth Low Energy-enabled wristband that replaces keys and passwords. Everykey ( http://everykey.com ) from the Cleveland, Ohio-based company of the same name, Everykey, is a fashionable band that can be instantly disabled if your Everykey ever gets lost or stolen. You call the team or go online to deactivate it. A message is immediately sent to all of your devices letting them know that they should not unlock for your wristband. The team would overnight you a new wristband at a discount. As the team says in their promotional video, it pretty much "unlocks your life." When the Everykey wristband is within range of a user's device, the wristband will allow the user to bypass that device's password or physically unlock it automatically. When the wristband is out of range, the device automatically re-enables security mechanisms.
They say their security is military-grade. (Everykey uses AES 128-bit encryption), and they also highlight an "obsession with design and usability." Fashion, they said, was their "north star." Color options were selected to reflect a unique personality. The band has a silicon exterior with a lightweight metal skeleton. Everykey works with Mac OS 10.9 (Mavericks), Windows 8.1, and Android 4.4 (KitKat). They are currently developing support for jailbroken versions of iOS as well as Ubuntu 14+ (Linux). The circuit board is powered by their custom bent lithium-polymer battery. The team said that you would need to charge it about once a month. After the battery runs out, you can charge Everykey using an included Micro USB to USB cable.

What does SN think about this project ?

I have enough microcontroller experience to know what I'm doing and know enough crypto to be really dangerous so in my infinite spare time I've been thinking of implementing my own "security dongle market clone number 35513153" which would use classic WWII enigma algo. I mean, technically, it is military grade, for gods sake half the planet was conquered by a military using that algo, so what could possibly go wrong? It would be a pretty good way to end up on hackaday. I'd probably hack together a horrific huge beast using arduino and shields rather then even trying to miniaturize. Primary problem is lack of spare time / better things to do. It wouldn't be very difficult. I'd probably do it the "wrong" way with regular high power bluetooth and a BT-serial instead of emulating a keyboard (because RFCOMM speaking breakout boards / shields are more common and cheaper than HID speakers, although I know HID speakers are available)
TLDR is VLM wants to implement WW2 Enigma machine on an arduino and market it as "military grade encryption" as a stunt.
