As much as I would like very much to have an open source hardware token, there’s a major downside to the nitrokey start and other STM32F103 gnuk devices. The microcontroller itself is not hardened at all in hardware. It would not be remotely infeasible to extract secrets from its hardware using relatively available tools. This is in contrast to a true smart card or a yubikey, which have tamper evidence.
