Hi, I followed this tutorial : https://www.nitrokey.com/documentation/openpgp-create-backup I only replaced the RSA key by NIST P-521. Here is my tryout… Factory reseting the key, just to be sure : [root@sysresccd ~]# gpg --card-edit gpg: directory '/root/.gnupg' created gpg: keybox '/root/.gnu…

Situation has not changed with latest version. Used GnuPG 2.2.25. Reported with logs from reproduction to GnuPG: https://dev.gnupg.org/T5163 Topic revived at (please continue discussion there): Unable to generate or move 521-bit ECC keys onto Nitrokey Pro 2

There is an issue with P521 here as well: NitroKey HSM 2 and secp521r1 vs 384.
