Talked about TLS, certificates, encryption in transit.
Start by defining HTTP and HTTPS at a high level, then focus on the key differences: security, encryption, and performance. Relate the answer to real-world implications, such as how HTTPS is essential for protecting user data and is now a standard for modern web applications.
Pro tip: Mention that HTTPS is not just about encryption but also about trust and SEO, and that modern browsers mark HTTP sites as 'not secure'. Also, note that HTTPS can have a slight performance overhead due to TLS handshake, but HTTP/2 and HTTP/3 mitigate this.
Briefly explain that HTTP is the foundation of data communication on the web, while HTTPS is the secure version using TLS/SSL encryption.
Highlight that HTTPS encrypts data in transit, preventing eavesdropping and man-in-the-middle attacks, whereas HTTP sends data in plaintext.
Acknowledge that HTTPS introduces a TLS handshake overhead, but modern optimizations like session resumption and HTTP/2 reduce latency.
Mention that HTTPS is required for many web features (e.g., geolocation, service workers) and is favored by search engines, while HTTP is deprecated for sensitive data.
Conclude that despite minor overhead, HTTPS is essential for security and trust, and the industry has largely moved to HTTPS-only.
