nitrokey-pro-firmware | Firmware for the Nitrokey Pro device

nitrokey-pro-firmware is a C library. nitrokey-pro-firmware has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

Nitrokey Pro, Start and HSM use the same hardware but different firmwares and different smart cards. The microprocessor being used is a STM32F103R8T6. The firmware is written in C, the desktop software Nitrokey App is written in C/C++. To develop the firmware of the Nitrokey Pro/Start/HSM you would need: * An original Nitrokey Pro/Start/HSM or better a development board such as the [Nucleo-F103RB] or the [Olimex STM32-H103]. Alternatively, get any other development board equipped with a STM32F103TB and 128KB flash. On request you can get a Nitrokey for development purposes from us. * An OpenPGP Card 3.4 available at [FLOSS Shop] or on request from us. (Of course, this is not necessary for Nitrokey Start which doesn’t contain a smart card.) If you use it with original Nitrokey hardware, you would need to cut it to Micro-SIM size. This can be done by using a special SIM card cutter or even with scissors. If you use a development board, you may solder the OpenPGP Card to the board directly by using some wires or you get yourself a smart card jack which you solder to the dev board instead. * To compile the firmware we recommend [ARM’s official GNU tools].
