The present invention provides an encryption method in which the encryption device stores data to be encrypted received via the input/output interface in its own memory, converts the data to be encrypted in the memory into a format required by the output device and transmits the converted data to the output device via the management interface, and the output device outputs the received information. The present invention also provides an encryption device for implementing the above method. The encryption device determines whether confirmation information has been received from a management interface, encrypts the data to be encrypted in the memory if the answer is positive, while performs no encryption or prompts to input correct confirmation information if the answer is negative. With the present invention, the user is allowed to view the contents to be actually encrypted, thereby avoiding such a case as signature counterfeiting or tampering. |
