About Certbot
By Toolradar Team·
Certbot gets free SSL certificates from Let's Encrypt and installs them automatically. Run a command, and your website gets HTTPS—no certificate authorities to deal with, no annual renewals to remember.
Plugins handle Apache and Nginx automatically. Renewal runs via cron or systemd. The certificates are legitimate and browser-trusted.
Server administrators who want HTTPS without the traditional certificate hassle use Certbot to automate what used to require vendors and annual fees.
