ACME (Automatic Certificate Management Environment) is the protocol Let's Encrypt created for automated certificate issuance. Instead of filling out forms and waiting for emails, ACME lets software request, validate, and receive certificates programmatically. The server proves domain ownership by responding to challenges — placing a specific file on the web server (HTTP-01) or creating a DNS record (DNS-01).
certctl speaks ACME natively, so it can request certificates from Let's Encrypt or any ACME-compatible CA without manual intervention.
