Dev
SSL Certificate Prompt Generator
The most common TLS outage is a certificate that expired because nobody set up renewal. The second is a guide that covered getting the cert but skipped installing it, or never tested automatic renewal. This tool generates a thorough fill-in prompt that asks an AI to cover all those steps. Pick the task — Let's Encrypt with Certbot, Self-signed for dev, CSR for a CA, or Wildcard certificate — and enter your domain. The prompt asks for the exact commands to run, where the cert and key files land, the nginx and Apache config lines to reference them, how to verify the certificate after install, and how to set up and test automatic renewal. Paste into your assistant and follow the steps on a Linux server.

FAQ
why does the prompt specifically ask about renewal
Let's Encrypt certificates expire after 90 days. The most common TLS outage is a certificate that expired because nobody set up automatic renewal, or set it up but never tested it. The prompt makes both setup and a dry-run test mandatory parts of the answer.
when is a self-signed certificate appropriate
Self-signed certificates are fine for local development and internal services where you control both client and server and can add the cert to the trust store. They trigger browser warnings on any public site because no trusted CA has vouched for them.
what is a CSR and when do I need one
A Certificate Signing Request bundles your domain name and public key for a certificate authority to sign. You keep the private key on your server and never share it — the CA receives only the CSR and returns a signed certificate.
