HTTPS

HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that encrypts data transmitted between a web browser and a server using SSL/TLS protocols. It ensures confidentiality, integrity, and authentication of web communications, protecting against eavesdropping, tampering, and man-in-the-middle attacks. HTTPS is essential for securing sensitive information like login credentials, payment details, and personal data on websites.

Also known as: HTTP Secure, HTTP over TLS, HTTP over SSL, SSL/TLS, Secure HTTP

Why learn HTTPS?

Developers should implement HTTPS on all websites to protect user data, comply with security standards (e.g., GDPR, PCI DSS), and improve SEO rankings, as search engines like Google prioritize secure sites. It is critical for e-commerce, banking, healthcare, and any application handling sensitive information to prevent data breaches and build user trust. HTTPS is also required for modern web features like service workers and geolocation APIs.
