Nitrokey Pro, Windows#
Connect your Nitrokey to your computer and confirm all dialogs so that the USB smart card device driver gets installed almost automatically. Windows may fail to install an additional device driver for the smart card. Its safe to ignore this warning.
Download and start the Nitrokey App.
Go to “Menu” -> “Configure” to change the User PIN (default: 123456) and Admin PIN (default: 12345678) to your own choices.
Your Nitrokey is now ready to use.
For many use cases described, it is necessary to have either OpenPGP or S/MIME keys installed on the device (see below).
There are two widely used standards for email encryption. While OpenPGP/GnuPG is popular among individuals, S/MIME/x.509 is mostly used by enterprises. If you are in doubt which one to choose, you should use OpenPGP.
