2.3.4 Loading the Certificate onto the Card

This step is optional. You may choose to store the certificate directly into your OpenPGP card. The benefit of doing so is that Scute will then be able to fetch the certificate from the card without having to look into the GPGSM store.

You need your certificate in the DER format. Export it from the GPGSM store with the following command:

$ gpgsm -o floppy-head.crt --export Floppy

Then, fire up the GnuPG card editor to transfer the certificate to the card (note that the writecert command is not listed in the editor’s online help):

$ gpg2 --card-edit

Application ID ...: D27600012301020000005000012340000
