What is HTTPS Everywhere?

The practice of securing all web traffic with TLS encryption, ensuring data integrity and privacy between browsers and servers.

HTTPS (HTTP over TLS) encrypts all communication between client and server, preventing eavesdropping, tampering, and man-in-the-middle attacks. Modern best practices mandate HTTPS for all pages, not just login or payment forms. Implementation requires obtaining TLS certificates (free from Let's Encrypt), configuring web servers for TLS, enabling HSTS (HTTP Strict Transport Security) headers, and redirecting HTTP to HTTPS. Google uses HTTPS as a ranking signal for SEO. HTTP/2 and HTTP/3 protocols effectively require HTTPS. Certificate management can be automated with tools like Certbot and ACME protocol.
