'crypto key generate rsa' necessary for SSH?

Answered Question
May 12th, 2010

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 firewall by 'show run', I didn't see this command by the way. Anyone can guide me how to check if my ASA already be enabled  'crypto key generate rsa' ?

Thank you all very much for reply.

I have this problem too.

Yes, it is necessary to generate the rsa key pair for SSH access.

Here is the command to check the keypair in your ASA:

show crypto key mypubkey rsa

Hope that helps.
