â„šī¸ About SSL Certificates

SSL (Secure Sockets Layer) certificates encrypt data between your browser and ruby-lang.org's server. A valid SSL certificate ensures that your connection is private and that you're communicating with the real Ruby-lang website.

Websites without valid SSL certificates may show browser warnings and are penalized in search engine rankings.
