To sign host's public keys there is the script 'generate_host_certificate.sh' to simplify the procedure.
The scripts does have the following options:

• -I
  • This takes the HOST_ID of the server.
  • e.g host.netdef.org
• -f
  • The file that contains all the keys.
• -V
  • Add the validity interval of a certificate
  • Per default a certificate is valid for one year.
  • More information can be found here: validity_interval
• -n
  • This flag restricts the certificate to a list of principals that the host is known by.

The output of 'generate_host_certificate.sh' is the certificate 'HOST_ID-cert.pub' that needs to be copied to the host. It is stored in the home directory '$HOME/signed_keys'.
