Your certificate and chain have been saved at:<br /> /etc/letsencrypt/live/test.t0e.org/fullchain.pem<br /> Your key file has been saved at:<br /> /etc/letsencrypt/live/test.t0e.org/privkey.pem<br /> Your cert will expire on 2019-04-30. To obtain a new or tweaked<br /> version of this certificate in the future, simply run certbot-auto<br /> again with the &quot;certonly&quot; option. To non-interactively renew *all*<br /> of your certificates, run &quot;certbot-auto renew&quot;<br /> - Your account credentials have been saved in your Certbot<br /> configuration directory at /etc/letsencrypt. You should make a<br /> secure backup of this folder now. This configuration directory will<br /> also contain certificates and private keys obtained by Certbot so<br /> making regular backups of this folder is ideal.<br /> - If you like Certbot, please consider supporting our work by:<br /> <br /> Donating to ISRG / Let&#039;s Encrypt: https://letsencrypt.org/donate<br /> Donating to EFF: https://eff.org/donate-le<br /> &lt;/pre&gt;</div>
