SSL/TLS certificate
The SSL/TLS certificate encrypts exchanges between visitors and the website (HTTPS) and proves its identity. It is issued by a certificate authority after a more or less thorough check: of the domain name only (DV), of the organization that owns it (OV), or extended validation (EV).
Free certificate issued by Let's Encrypt: valid for a few months, it is renewed automatically.
