Automate issuance and renewal with ACME
IDigiTrust natively supports ACME. With acme.sh or Certbot you can fully automate request, deploy and renewal.
Install acme.sh
curl https://get.acme.sh | sh
Issue (DNS mode)
acme.sh --issue --dns dns_cf -d example.com -d *.example.com
Install into Nginx
acme.sh --install-cert -d example.com \ --key-file /etc/nginx/ssl/example.key \ --fullchain-file /etc/nginx/ssl/example.crt \ --reloadcmd nginx -s reload
A cron job renews automatically before expiry.
