Use the ACME DNS-Challenge to get a TLS certificate

This technical article details the ACME protocol's DNS-01 challenge for obtaining TLS certificates from Let's Encrypt. It compares different ACME challenge types (HTTP-01, DNS-01, TLS-SNI-01, TLS-ALPN-01) and focuses on the DNS method, which allows for automation via DNS provider APIs and is ideal for development environments or issuing wildcard certificates without a publicly accessible web server.
