It's always promising what's happening with the NitroKey. But on the other side it is disillusion. I hoped that the usage of the NitroKey with OpenPGP will be much more effective since the decryption of something took five time longer than with a YubiKey (and I will change from it to NitroKey). But than I cannot update the firmware because of the error "LibraryNotFoundError('Error detecting the version of libcrypto')" of pynitrokey binary for linux (I use devuan/debian). I will wait another longer time in the hope to get a useful product. As I said it is always promising what happens.
