Cleaning up challenges
IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
  /etc/letsencrypt/live/trustregistry.org/fullchain.pem
  Your key file has been saved at:
  /etc/letsencrypt/live/trustregistry.org/privkey.pem
  Your cert will expire on 2021-06-10. To obtain a new or tweaked
  version of this certificate in the future, simply run certbot
  again. To non-interactively renew *all* of your certificates, run
  "certbot renew"

Prepare pfx file

openssl pkcs12 -export -in cert.pem -inkey privkey.pem -out trorg.pfx
