# LSLB | Let’s Encrypt

In this section, you'll learn more about **RELIANOID 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, RELIANOID Application Delivery Controller requires a direct connection to Let's Encrypt services to create **Certificates for Hosts** (for example *www.relianoid.com*). This communication between RELIANOID ADC and Let's Encrypt is done through **ACME** protocol over an encrypted secure protocol.

The certificate list includes the following details:
  Common Name. A Fully Qualified Domain Name (FQDN) pointing to a server. The domain may follow the format: test3.test.relianoid.io, domain.com, or mail.domain.com
  Issuer. A certificate authority that has signed the certificate.
  Domains. Domain(s) to be certified by the authority Issuer.
  Status. Color indicators that show the current status of a certificate:

- **Green**. The certificate is valid.
- **Yellow**. The certificate will soon expire and its renewal is pending.
- **Red**. The certificate has expired.
- **Orange**. Waiting for approval, to be issued by Let's Encrypt.
- **Gray**. The certificate is invalid.

Autorenewal. This check is enabled if the certificate is not a wildcard.
  Creation. The date the certificate is issued.
  Expiration. The date the certificate expires.
  Actions. Use these actions for each certificate:

- Create certificate: Shows a form used to create the certificate.
- Delete. Deletes the Certificate from the local Storage and the Remote Let's Encrypt Certificate Authority.
- Autorenewal. When this option is activated, the appliance will be renewed days before the expiration date. For this to work, the appliance must be connected to the internet.
