SSL Cafe

YOUR FIRST CUP

Start with the question you have.

A clear route through a technical subject. Choose the path that fits the job in front of you.

01

I’m learning the basics

Start with the connection itself, then work out how your website’s certificate is managed. You do not need to begin with command-line tools.

  1. HTTPS, TLS and certificates: a practical map
  2. Choosing a certificate for your website
  3. SSL/TLS Glossary
02

Something isn’t working

Pick the symptom that matches what you’re seeing. Record the exact hostname and error before changing anything.

  1. Troubleshooting an expired website certificate
  2. Diagnosing a certificate hostname mismatch
  3. Finding certificate chain problems
03

I’m responsible for keeping it running

Build a renewal process with clear ownership, deployment checks and a way to spot failures.

  1. A practical certificate renewal plan
  2. How ACME certificate automation fits together
  3. Checking HTTPS after a hosting or domain change

Before you follow an operational guide

  • Identify the actual hostname and who operates the website, host, DNS and any CDN.
  • Work out what you can safely inspect and what needs your provider’s help.
  • Read the prerequisites before copying a command or changing a configuration.
  • Keep private keys, passwords and account tokens out of public support requests.

SSL Cafe explains the decisions and moving parts. A guide is not evidence that your particular website has been inspected.
