O.K. here I’m again.
I’ve been working on the Nitrokey Pro under CentOS for a while. Since there are unfortunately no more recent packages of gnupg2-smime for CentOS 7, there are the following possible solution scenarios for me:
- even create a current RPM package for gnupg2-smime, or
- change from CentOS 7 to Fedora 29, or
- create PGP keys manually and then move them to the card.
I chose option three and documented my results here: https://wiki.mailserver.guru/doku.php/centos:nitrokey:pro
If something should be unkar, or someone has improvement wishes, then simply give it to me!
