Created this issue to make sure the patch doesn't get lost.

i tried to invoke from the --card-edit menu the keytocard function within batch
file. But that seams not work.

Which is a document feature —card-edit is a interactive tool.

To make it working, I would try to implement —quick-keytocard in the same style
like —quick-addkey.

I looked around in gpgme and didn’t not found any entry point which allows me to
do keytocard.

My question is, if i try now to implement quick-keytocard, would you accept my
patch?

Or is there any other idea how to send a key from gpg to a smartcard within a batch?

I currently only know one bigger obstacle keytocard needs a passphrase and the
adminpin both a gather via
pinentry. This leads to a extension to the batch mode command line (--no-tty
--pinentry-mode loopback --passphrase-fd).

Now —quick-keytocard is working for me. I can pass the passphrase
and the adminpin down. I solved it by enabling the multiple use of
—passphrase-fd/file

here the patch for the passphrase change
