Cryptography & Transport

HTTPS

HTTPS (HyperText Transfer Protocol Secure) is the encrypted version of HTTP, using TLS to secure data between a browser and a web server. It ensures that passwords, credit card numbers, and other sensitive data cannot be intercepted in transit. Browsers display a padlock icon for HTTPS sites and show warnings for HTTP pages. HTTPS is also a ranking factor for search engines and a prerequisite for many modern browser APIs.
