Yep. Creating RSA-1024 or RSA-2048 directly on this card works fine.

I don't know, if this is correct, but when I do create an RSA-4096 key with GPG directly on my Gentoo notebook and move this one to the card with "keytocard", it works and a RSA-4096 is shown on my card. Seems to work somehow, that RSA-4096 is possible?
