Cannot SSH into PIX/ASA firewall

Issue:
When attempting to SSH into a PIX/ASA firewall you receive the following error on the client

ssh_exchange_identification: Connection closed by remote host

Investigating the log on the PIX/ASA will yield a corresponding error:

Fail to establish SSH session because RSA host key retrieval failed.

Cause:
The issue is the result of a corrupt or missing RSA key on the firewall.

Resolution:
You need to generate a new RSA key on the firewall.

Magic juju (from either SDM or a prompt):

conf t
ca generate rsa key 1024
wr mem
copy run start
