DES
DES (Data Encryption Standard) is a typical
symmetric-key cryptographic algorithm that divides
data in to 64-bit blocks and then encrypts each
block using a 56-bit key.
•
3DES
3DES (Triple Data Encryption Standard) is a high
level of encryption in which DES encryption is
repeated threefold.
A hash symbol (
g
) appears to the right of the selected encryption
method.

After completing the selection, press
[Complete]
(
[Right Select]
).
The selected encryption method is set and the SSL menu reappears.
Once you have set an encryption method, and asterisk (*) appears in
front of this menu option.
IPP over SSL (SSL Server IPP over SSL setting)
IPP over SSL is an encryption function that uses SSL for communications between users and servers in network printing.
To use IPP over SSL, both server and client must support the protocol. The default setting is
Off
.

In the SSL Setting menu, press
or
to select
IPP over SSL
.

Press
[OK]
. The
IPP over SSL
screen appears.
3
Press
or
to select whether IPP over SSL is enabled.
4
Press
[OK]
. The IPP over SSL setting is set and the SSL Setting
menu reappears.
IMPORTANT
Symmetric-key cryptography, because it uses
the same key for both encryption and decryption, uses the
same key in both directions when encrypted data is
exchanged. Accordingly, to prevent the key from being
divulged, key transfer and storage must be very strictly
managed.
