Your certificate and chain have been saved at: /etc/letsencrypt/live/superuser.web.id/fullchain.pem Your key file has been saved at: /etc/letsencrypt/live/superuser.web.id/privkey.pem Your cert will expire on 2020-01-24. To obtain a new or tweaked version of this certificate in the future, simply run certbot-auto again with the "certonly" option. To non-interactively renew *all* of your certificates, run "certbot-auto renew" - Your account credentials have been saved in your Certbot configuration directory at /etc/letsencrypt. You should make a secure backup of this folder now. This configuration directory will also contain certificates and private keys obtained by Certbot so making regular backups of this folder is ideal. - If you like Certbot, please consider supporting our work by: Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate Donating to EFF: https://eff.org/donate-le |
