HTTPS and SSL — Why the Lock Icon Matters
What HTTPS does, Let's Encrypt, mixed content, and why encryption in transit is non-negotiable
You've seen the little lock icon in your browser's address bar. You might know it has something to do with security. But what exactly does it mean, and why should you care?
HTTPS is the encryption layer that protects data as it travels between your users and your server. Without it, everything — passwords, personal data, session tokens — is sent in plain text that anyone on the network can read.
HTTP vs HTTPS: The Difference
HTTP (HyperText Transfer Protocol) sends data in plain text. Anyone between the user and the server can read it — the WiFi router, the internet service provider, or an attacker on the same network.
HTTPS (HTTP Secure) encrypts all data in transit. Even if someone intercepts the traffic, they see gibberish instead of readable data.
