retrieve_certificate stack ~dns_key ~hostname ~key_type ~key_data ~key_seed ~bits server_ip port
generates a private key (using key_type
, key_data
, key_seed
, and bits
), a certificate signing request for the given hostname
and additional_hostnames
, and sends server_ip
an nsupdate (DNS-TSIG with dns_key
) with the csr as TLSA record, awaiting for a matching certificate as TLSA record. Requires a service that interacts with let's encrypt to transform the CSR into a signed certificate. If something fails, an exception (via Lwt.fail
) is raised. This is meant for unikernels that require a valid TLS certificate before they can start their service (i.e. most web servers, mail servers).
