• Configure Lets Encrypt Digital Ocean

  A website’s domain must have SSL/TLS encryption if it intends to get visitors. SSL/TLS certificates provide a strong connection among web servers and browsers. Earlier, security wasn’t a major concern. It was relatively common for websites to deliver data via the established HTTP protocol. Nowadays, the channel used to communicate with the server must be secured, though, because cybercrimes including identity theft, credit card fraud, and espionage are on the rise.

  A Certificate Authority (CA) called Let’s Encrypt offers free SSL/TLS certificates, enabling HTTPS encryption on web servers. It is domain verified, so a dedicated IP Address is not necessary. It is usually advised to have an SSL certificate enabled on your website to improve your SEO ranking, particularly on Google.
