| − | IMPORTANT NOTES:
| |
| − | - Congratulations! Your certificate and chain have been saved at:
| |
| − | /etc/letsencrypt/live/asmith15.ops345.ca/fullchain.pem
| |
| − | Your key file has been saved at:
| |
| − | /etc/letsencrypt/live/asmith15.ops345.ca/privkey.pem
| |
| − | Your cert will expire on 2022-02-16. 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"
| |
| − | - 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:
