- **eab** specifies an External Account Binding which may be required with some ACME CAs.
- **trusted_roots** is one or more root certificates (as PEM filenames) to trust when connecting to the ACME CA server.
- **dns** configures the DNS challenge.
- **propagation_timeout** is a [duration value](/docs/conventions#durations) that sets how long to wait for DNS TXT records to propagate. Default 2 minutes.
- **resolvers** customizes the DNS resolvers used when performing the DNS challenge; these take precedence over system resolvers or any default ones.
- **preferred_chains** specifies which certificate chains Caddy should prefer; useful if your CA provides multiple chains. Use one of the following options:
- **smallest** will tell Caddy to prefer chains with the fewest amount of bytes.
