How it works

Understanding SSL/TLS certificates

SSL/TLS certificates are the foundation of secure communication on the internet. When you visit a website over HTTPS, your browser and the web server perform a handshake where the server presents its certificate to prove its identity. The certificate also establishes the encryption keys used to protect data in transit.

A valid SSL certificate matters for more than just security. Search engines use HTTPS as a ranking signal, and browsers actively warn users when visiting sites without valid certificates. Expired or misconfigured certificates can lead to lost traffic, reduced trust, and lower search rankings.
