    In reply to part 2 of your question there are 2 options I'm assuming this is what your trying to figure out I could be wrong as your question is unclear at this point.

    Set Up an IOS Router or Switch as SSH Client

    hostname carter

    aaa new-model

    username cisco password 0 cisco

    crypto key generate rsa

    ip ssh time-out 60

    ip ssh authentication-retries 2

    line vty 0 4

    transport input SSH

    Setup an IOS Router as an SSH server that performs RSA based User Authentication

    Router(config)#hostname <host name>

    Router(config)#ip domain-name <Domain Name>

    Router(config)#crypto key generate rsa

    Router(config)#ip ssh pubkey-chain

    Router(conf-ssh-pubkey)#username <user name>

    Router(conf-ssh-pubkey-user)#key-string

    Router(conf-ssh-pubkey-data)#key-hash ssh-rsa <key ID>

    Router(conf-ssh-pubkey-data)#end
