ssh private keys stored on home server

Where in the world are the ssh private keys stored on the home server? I know the public keys are renamed to authorized_keys under the /export/home/[user]/.ssh directory on the remote server.

The local home directory in the .ssh subdirectory, which in ksh can be ~/, so try:

ls ~/.ssh

The keys public and private should exist there:
id_rsa - private key
id_rsa.pub - public key
