2. Public Key & Signature

Frequently Asked Questions (FAQ)
No. A Certificate Signing Request contains only your public key and structural metadata. Your private key stays safely on your server.
The Common Name represents the fully qualified domain name (FQDN) you intend to secure with your SSL/TLS certificate (e.g., `www.example.com` or `*.example.com`).
