Certificate for hostname 'host.localdomain', in file (or by nickname):
/etc/pki/tls/certs/localhost.crt
The certificate needs to be renewed; this can be done
using the 'genkey' program.
Browsers will not be able to correctly connect to this
web site using SSL until the certificate is renewed.sudo rm /etc/pki/tls/certs/localhost.crt sudo rm /etc/pki/tls/private/localhost.key
