Nitrokey Pro, Linux#
To access the OpenPGP smart card of the Nitrokey, install the package libccid. On Debian/Ubuntu based Distributions type in terminal: sudo apt-get update && sudo apt-get install libccid
If your distribution has a rather old version of libccid (<1.4.21) you have to add the device information by yourself (for example if you are using Ubuntu 14.04 or older). In this case please follow these instructions.
Your Nitrokey is now ready to use.
Note: 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.
To learn more about how to use OpenPGP for email encryption with the Nitrokey, please refer to chapter OpenPGP Email Encryption.
To learn more about how to use S/MIME for email encryption with the Nitrokey, please refer to chapter S/MIME Email Encryption.
