Let’s Encrypt certificates list

In this section, you’ll learn more about ZEVENET Application Delivery Controller. This application has been integrated with the Let’s Encrypt system to manage SSL certificates, and use them in the reverse proxy implemented in the load balancing module LSLB with the HTTPS profile.

Let’s Encrypt is a free, open, and automated certificate authority (CA) accessible as a public service on the Internet and built to simplify the acquisition of SSL/TLS digital certificates proving a site’s authenticity, while also providing encryption.

Since Let’s Encrypt is a service available on the web, ZEVENET Application Delivery Controller requires a direct connection to Let’s Encrypt services to create Certificates for Hosts (for example www.zevenet.com) or Wildcard Certificates (for example *.zevenet.com). This communication between ZEVENET ADC and Let’s Encrypt is done through ACME protocol over an encrypted secure protocol.
