A digitally signed message, protected with a chain of certificates from the sender's immediate certifier up through an ultimate certifier, is transmitted to a recipient together with the entire certificate chain. The entire certificate chain is stored in a single signer file accessible by the sender. Drag-and-drop gestures of a graphical user interface are used by the sender to sign and certify the message, and an icon is provided on the recipient's display to initiate verification.
