While using some software that tries to simultaneously encrypt and sign some piece of data, I realized that I am not able to do so.
I can sign
gpg -s -u MYID output.txt
gpg -e -r MYID output.txt
but not both:
gpg -e -r MYID -s -u MYID output.txt gpg: signing failed: Conditions of use not satisfied gpg: output.txt: sign+encrypt failed: Conditions of use not satisfied
I checked by creating a software key that I am able to do that operation without using the Nitrokey Pro 2.
Is this something hardware related? Any workarounds?
