Overview

A certificate used to secure HTTPS traffic.

Definition

A certificate used to secure HTTPS traffic.

Real-world example

Browsers show a padlock for https://app.example.com because a valid certificate chains to a public CA trusted by operating systems.

Common mistake

Using self-signed certificates in production without distributing your CA to clients.

Better-PaaS in practice

Public certificates come from Let's Encrypt via Caddy. No manual certificate upload is required for standard domains.

FAQ

Is SSL certificate only relevant to Better-PaaS?

No. SSL certificate appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
