2
Press [OK]. The Encryption screen appears.
3
Press or to select the encryption method to be used and then
press [OK].
The options available in Encryption are as follows:
• AES (SSL Server AES setting)
AES (Advanced Encryption Standard) was developed to replace
DES as the standard encryption as the safety of DES has declined.
AES is a block encryption system that uses 128-bit blocks and an
SPN structure (a typical structure for repeated encryption) with
three selectable key lengths of 128, 192 and 256 bits.
• 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.
4
After completing the selection, press [Complete] ([Right Select]).
The selected encryption method is set and the SSL menu reappears.
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 On.
1
In the SSL Setting menu, press or to select IPP over SSL.
2
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.
