HTTPS

HTTPS (Hypertext Transfer Protocol Secure) is an extension of HTTP that adds encryption and authentication to web communications, ensuring data privacy and integrity between clients and servers. It uses TLS (Transport Layer Security) or its predecessor SSL (Secure Sockets Layer) to encrypt data in transit, preventing eavesdropping and tampering. 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, HTTPS/SSL, Secure HTTP

Why learn HTTPS?

Developers should learn and use HTTPS to build secure web applications that protect user data and comply with privacy regulations like GDPR. It is critical for e-commerce sites, banking platforms, and any service handling sensitive information to prevent man-in-the-middle attacks and data breaches. Additionally, modern browsers flag non-HTTPS sites as insecure, and search engines like Google prioritize HTTPS sites in rankings, making it a standard for web development.
