The configuration can be read from a Yubikey-4 but not be written.

shows an appropriate error message.

Having the version of the yubikey is important to select which other

formfactor of a Yubikey 4 and instead use 0 for our serial number
prefix. This does not affect app-openpgp becuase there we use the app
specific serial number.

The PGP desktops exported secret keys are really stupid. And they

out (section 11.2):
[...] Implementations SHOULD include self-signatures on any user
IDs and subkeys, as this allows for a complete public key to be
automatically extracted from the transferable secret key.
Implementations MAY choose to omit the self-signatures, especially
if a transferable public key accompanies the transferable secret
key.
Now if they would only put the public key before the secret
key. Anyway we now have a workaround for that ugliness.

When importing an invalid secret key ring for example without key
binding signatures or no UIDs, gpg used to let gpg-agent store the
secret keys anyway. This is clearly a bug because the diagnostics
before claimed that for example the subkeys have been skipped.
Importing the secret key parameters then anyway is surprising in
particular because a gpg -k does not show the key. After importing
the public key the secret keys suddenly showed up.
This changes the behaviour of

This has been tested with gpgsm and RSA keys. For ECC keys only
partly tested using the sample OpenPGP nistp256 and nistp384 keys
because gpgsm does not yet support ECC certificates and thus we can't
write the certificates to the cert object after a writekey. Note that
they nevertheless show up in "gpgcard list" because gpg-card searches
for them in gpg and gpgsm. However, this does not work completely.
