With backup and restore import/export options all should be set for a long time. I guess this bug can be closed.

  • Causes build_packet_and_meta() to be used instead of build_packet()
    • This variant also writes the meta data using ring trust packets.

        • Ring trust packets are implementation defined and have always been used in gpg to cache the signature verification status.
        • Ring trust packets are only exported with the export option "backup" and only imported with the import option "restore".
        • As a side-effect of this patch the signature status cache works again and "gpg --check-sigs" is thus much faster.

Sure. I'll mark that to be added!

Certificate though has a nicer connotation to it and definitely feels like it has the connotation of something to be shown off to other people and displayed on walls, which I really like.

Whoops, going to repost.

The correct technical term is OpenPGP Public Keyblock but I better shut up on the certificate vs. Public key(block) question.

I can only tell that the term "Certificate" is exactly what Kleopatra was trying to use consistently in the GUI. For Kleopatra it is also important because it tries to work with both X509 "certificates" and OpenPGP "public keys".
