What is Let’s Encrypt?
Internet Security Research Group runs a non-profit and automated certificate authority called Let’s Encrypt. They also provide X.509 certificates for Transport Layer Security encryption for free. Let’s Encrypt allows you to install a free, trusted SSL certificate on the website and enjoy the benefits of enhanced security. A self-signed SSL certificate is also free and secure but not yet verified, whereas Let’s Encrypt certificate is a fully verified and recognized certificate, which also displays the padlock icon in the address bar of web browsers.
A plugin in Plesk allows you to manage Let’s Encrypt SSL certificates.
