# Script to deploy certificates to Palo Alto Networks PANOS via API
# Note PANOS API KEY and IP address needs to be set prior to running.
# The following variables exported from environment will be used.
# If not set then values previously saved in domain.conf file are used.
#
# Firewall admin with superuser and IP address is required.
#
# export PANOS_USER="" # required
# export PANOS_PASS="" # required
# export PANOS_HOST="" # required
# This function is to parse the XML
