CRYPTO KEY GENERATE HOSTKEY

crypto key generate hostkey
Overview This command generates public and private keys for the SSH server using either an
RSA or DSA cryptography algorithm. You must define a host key before enabling
the SSH server. Start SSH server using the service ssh command. If a host key exists
with the same cryptography algorithm, this command replaces the old host key
with the new key.
This command is not saved in the device configuration. However, the device saves
the keys generated by this command in the non-volatile memory.
crypto key generate hostkey {dsa|rsa|rsa1} [<768-32768>]
Syntax
Default 1024 bits is the default key length. The DSA algorithm supports 1024 bits.
Mode Global Configuration
Examples To generate an RSA host key for SSH version 2 connections that is 2048 bits in
length, use the commands:
awplus#
awplus(config)#
To generate a DSA host key, use the commands:
awplus#
awplus(config)#

Parameters Description
dsa
Creates a DSA hostkey. Both SSH version 1 and 2 connections can
use the DSA hostkey.
rsa
Creates an RSA hostkey for SSH version 2 connections.
rsa1
Creates an RSA hostkey for SSH version 1 connections.
<768-32768>
The length in bits of the generated key. The default is 1024 bits.
