What is HTTPS?

1 min read Updated 2026-02-05

HTTP Secure. The encrypted version of HTTP using TLS. All modern web applications should use HTTPS to protect data in transit between client and server.

Understanding HTTPS

HTTPS provides three key security properties: encryption (data can't be read), integrity (data can't be modified), and authentication (you're talking to the right server). It's essential for protecting login credentials, personal data, and preventing man-in-the-middle attacks.

Examples

  • Secure login forms that protect password transmission
  • E-commerce sites protecting payment information
  • API endpoints requiring encrypted communication

How to Prevent

  • Enforce HTTPS for all pages, not just login
  • Use HTTP Strict Transport Security (HSTS)
  • Redirect HTTP to HTTPS at the server level
  • Use TLS 1.2 or 1.3 only
  • Configure proper certificate chains
