Certbot is the new Client from Let’s Encrypt. It’s the successor of the previews letsencrypt-auto Tool. With a simple Webserverconfiguration it’s easy to issue and renew certificates.
In the past Let’s Encrypt was only available via an invitation or by signing up to a waiting list. Starting with today Let’s Encrypt entered public beta meaning everybody can now start creating their own free certificates. General information regarding Let’s Encrypt and the differences over other CAs are covered in the article: “Let’s Encrypt initiative enters beta stage on December 3rd 2015“. Now we will start to create our own free domain validated certificates.
It’s always been a good idea using HTTPS for forms, sending personal data through the web. For many smaller websites and blogs this was often to expensive and to complex to set up. Let’s Encrypt intends to change that.
