I cannot generate a RSA SSH key on the device

SSH, OpenPGP, GPG

When I run the command from the instructions.

onlykey-agent user@host -e rsa -sk RSA2

You have to load RSA keys, those are not generated on device.

It is only not possible to generate RSA keys on this device. RSA keys can only be imported. ECC keys can be generated on the device.
