Oct 02, 2015 (Optional) Specifies that the RSA key pair can be exported to another Cisco device, such as a router. Modulus modulus-size (Optional) Specifies the IP size of the key modulus.By default, the modulus of a certification authority (CA) key is 1024 bits. The recommended modulus for a CA key is 2048 bits.

Choose Configuration Properties Device Administration Password in order to change the Telnet password with ASDM. Choose Configuration Properties Certificate Key Pair, click Add and use the default options presented in order to generate the same RSA keys with ASDM. Choose Configuration Properties. Crypto key generate rsa. For these key to work, you should have a hostname/domain-name configured on the ASA as well (unless you configure a dedicated RSA keys). So basically, configure a hostname, domain name and generate the RSA key pair: hostname NAMEOFASA. Domain-name NAMEOFDOMAIN. Crypto key generate rsa. Accept the default of 1024.

Cisco Generate Crypto Key

Whelton Network Solutions is an IT service provider.

Try this:

/final-draft-9-key-generator.html. username <USERNAME> password <PASSWORD> encrypted privilege 15
!
crypto key generate rsa modulus <<MODULUS_SIZE>
ssh version 2
!
ssh <IPADDRESS_SUBNET_MASK> <INTERFACE>
!

# So here's an example.
username admin password Cisco123 encrypted privilege 15
!
crypto key generate rsa modulus 1024
!
ssh 192.168.0.0 255.255.255.0 INSIDE
ssh version 2
!

So to explain, create a local user (you can create multiple accounts), please try not to use admin as it's guessable!.

Generate aes 256 key online. Generate the actual key the client will use to SSH server.

Tell the ASA from what IP address range SSH sessions can be opened from and on which interface, again you can one for the inside, outside or any other interface you have set up.

Tell the ASA to use SSH version 2.
