GNOME Keysign allows signing OpenPGP keys comfortably and securely via the local network or Bluetooth.
It can scan another key's barcode and transfer the key securely, allowing for casual two-party key signing sessions. It follows best practises by sending the encrypted signatures to the UIDs of a key using the Email client the user configured to use.
