USB key for password entry

R00KIE · 2015-10-19 10:10:06

I was trying to find something similar to Yubikey[1] without all the "advanced" features and maybe with a lower price point but I haven't been able to find anything.

My requirements are usb device that emulates a keyboard and either types a password when pressing a button or just dumps the password upon connection and that the password can be easily configured from linux (of course). It could be something similar to this [2-3] but where the keystroke it sends can be reconfigured.

Does anyone know of something like this? Preferably cheaper than the Yubikey.

In case anyone is wondering the idea was to use this to input a password to unlock a luks volume or for pre boot authentication of a self-encrypting drive.

You could build one of these http://hackaday.com/2012/03/05/usb-dong … t-have-to/

I realise that you are asking for just plain passwords, but there are also these which are pgp based. There is the FST-01 which runs gnuk and is by the Free Software Initiative of Japan. This is also the nitrokey in various flavors https://shop.nitrokey.com/shop

Thanks for the suggestions. I did think about doing one myself as you pointed in the first link, but I know the end result (most probably) wouldn't be pretty, and having no previous experience with usb/hid it might take quite a while to get it working, even if borrowing code from other projects.

I really want something that supports plain passwords, as the main usage now would be with pre boot authentication of a self-encrypting drive using sedutil[1], which for now only supports keyboard input. My only problem with the yubikey devices is the price, a bit too much for the intended purpose for now, but if buying one the edge version seems to be the better investment.

Other than these I am unsure of anything else (well there is the mooltipass but that is way too expensive).

Good luck with your search

Small update, I have bitten the bullet and bought a yubikey-edge (with the 20% github discount). For now it is something that works out of the box and should be relatively well supported.

In the meantime I have stumbled upon some leonardo beetle boards[1] that should ease the development of something like I was looking for.

For AVR microcontrollers there is a nice USB library [1] which helps quite a lot. I think there is even a hid example included.
