What this card says
What each one is
HTTP: web traffic in plain text on port 80.
HTTPS: HTTP inside TLS encryption on port 443.
How they differ
On HTTP, anyone on the path can read data.
HTTPS encrypts it and proves the site with a certificate.
Example
Chrome marks HTTP pages 'Not secure' and shows a padlock for HTTPS.
Use when
Always HTTPS. Get a free certificate and redirect HTTP to HTTPS.
