Cisco Asa Ssh Crypto Key Generate Rsa

Solved: I read from the manual that the key pair will be used for SSH but just wonder does the command 'crypto key generate rsa' is necessary to enable SSH on ASA? I can access to my firewall via SSH but when I checked in the configuration on ASA. Config t crypto key generate rsa exit Then ssh to the router and complete the config. Or just enable telnet if you can get away with it. Config t vty 0 4 transport input ssh telnet exit I have a perl script that does this to reset enable passwords.

You can access Cisco ASA appliance using Command Line Interface (CLI) using either Telnet or SSH and for web-based graphical management using HTTPS (ASDM) management. Telnet uses TCP port 23 and is not secure. Secure Shell (SSH) on the other hand uses port 22 and is secure. SSH uses public key cryptography to authenticate remote user. You can configure SSH access in Cisco ASA device using the steps shown here.
