Abstract

An encryption device which enables a client not having an encryption function to easily use a function of encrypted mail without carrying out a management of certification and a key and an encryption and a decryption. When an Internet facsimile machine transmits electronic mail to an encryption device, the encryption device converts the received electronic mail into encrypted mail and transmits to a mail server. When another Internet facsimile machine transmits data including a part to be encrypted and transmission destination information as a main body of mail to an encryption and decryption I/F of the encryption device, the encryption device encrypts the main body of the received mail under a prescribed encryption method and sends back to the other Internet facsimile machine. Accordingly, the other Internet facsimile machine can format encrypted data into encrypted mail and transmit to a remote Internet facsimile machine.
