A method of using hardware-type electronic signature in e-mail handling system includes the steps of a) connecting a USB hardware element to a sender end system, using a serial number assigned to the USB hardware element to encode and produce a hardware-type electronic signature, and registering the produced hardware-type electronic signature at a receiver end system; b) using the hardware-type electronic signature at the sender end system to encode and format an original e-mail, so as to produce a packet e-mail, and transmitting the packet e-mail to a selected receiver; c) verifying the hardware-type electronic signature at a receiver end system on receipt of the packet e-mail; and d) decoding the received packet e-mail and reducing the same to the original e-mail when the hardware-type electronic signature has been verified as correct at the receiver end system.
