Use the Security > SSH > Host-Key Settings page to generate a host
public/private key pair used to provide secure communications between an
SSH client and the switch. After generating this key pair, you must provide
the host public key to SSH clients and import the client’s public key to the
switch as described in the section “ Importing User Public Keys .”

:
A host key pair must be configured on the switch before you can
enable the SSH server. See “ Configuring the SSH Server .”

These parameters are displayed:
Public-Key of Host-Key – The public key for the host.
RSA (Version 1): The first field indicates the size of the host key
(e.g., 1024), the second field is the encoded public exponent (e.g.,
65537), and the last string is the encoded modulus.
DSA (Version 2): The first field indicates that the encryption method
used by SSH is based on the Digital Signature Standard (DSS). The
last string is the encoded modulus.
Host-Key Type – The key type used to generate the host key pair
(i.e., public and private keys). (Range: RSA (Version 1), DSA
(Version 2), Both; Default: Both)
The SSH server uses RSA or DSA for key exchange when the client first
establishes a connection with the switch, and then negotiates with the
client to select either DES (56-bit) or 3DES (168-bit) for data
encryption.
