256 KB of memory to support hardened crypto implementations and, later, additional features such as OpenPGP or SSH.įor the maintenance actions description, like firmware release or signing, look into MAINTAINERS.md.Flash protection from both external use and untrusted code segments.Security isolation so only simple & secure parts of code can handle keys.True random number generation to guarantee random keys.It offers the following security features. Nitrokey FIDO2 is based on the STM32L432 microcontroller. If you like (or want to learn) hardware instead, you can run the firmware on the NUCLEO-L432KC development board.
The main implementation is for STM32L432, but it is easily portable.įor development no hardware is needed, it also runs as a standalone application for Windows, Linux, and Mac OSX.
This repository contains the firmware, including implementations of FIDO2 and U2F (CTAP2 and CTAP) over USB and NFC.
It protects you against phishing and other online attacks. Nitrokey FIDO2 is an open source security key which supports FIDO2 and U2F standards for strong two-factor authentication and password-less login.
