Expand description

Obtain a signed certificate from the ACME provider at directory_url for the DNS domains.

The secret for the challenge is passed as a ready to use certificate to set_auth_key(domain, certificate)?. This certificate has to be presented upon a TLS request with ACME ALPN and SNI for that domain.

Provide your email in contact in the form mailto:admin@example.com to receive warnings regarding your certificate. Set a cache to remember your account.
