How to check the fingerprint of an SSH key
This is from an email from Gary:
Did you have occasion to reboot the server?
I have noticed the generation of new SSH keys during reboot.
I have also noticed that some distros are configured to automatically
replace the SSHD key periodically.
ssh_host_rsa_key is a PEM containing the private key
ssh_host_rsa_key.pub contains one line of the form: ssh-rsa
To show the fingerprint use: ssh-keygen -l -f ssh_host_rsa_key.pub
