About Keysign
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.
