well it was advertised that the yubikey4 (and the 4nano) offers 4096 bit keys.

but the key generation assisatant (which is surely a nice choice because your private key goes directly to the yubikey, (or at least it should)) doesnt offer 4096bit keys but for some or another really weird reason I can generate 1024 bit keys, even though those are REALLY bad and discouraged everywhere.

so might it be possible for the PIV Manager to make 4k keys?

Regards, My1

NIST does not yet specify 4096 as a supported algorithm. Until that happens, a 4096 RSA option will not be added to the PIV Manager. The hardware itself is capable of 4096 (Docker uses 4096). OpenPGP also supports 4096 RSA.
