SSH Server Configuration
SSHv1 
Encryption 
Algorithms
Enables or disables 
DES
, and displays the status (always enabled) of 
Blowfish
, two encryption algorithms (block ciphers) compatible with 
SSH, version 1, clients.
DES
: The key length is 56 bits.
Blowfish
: The key length is 128 bits. You cannot disable this algorithm.
N
OTE
:
Not all SSH clients can use every algorithm. If your SSH client 
cannot use 
Blowfish
, you must also enable 
DES
.
SSHv2 
Encryption 
Algorithms
Enables or disables the following encryption algorithms (Block Ciphers) 
that are compatible with SSH version 2 clients.
3DES
 (enabled by default): The key length is 168 bits.
Blowfish
 (enabled by default): The key length is 128 bits.
AES 128
: The key length is 128 bits.
AES 256
: The key length is 256 bits.
N
OTE
:
Not all SSH clients can use every algorithm. Your SSH client 
selects the algorithm that provides the highest security from among the 
enabled algorithms that it is able to use. (If your SSH client cannot use 
either of the default algorithms, you must enable an AES algorithm that it 
can use.)
