Signature

val retrieve_certificate : 
  ?ca:[ `Production | `Staging ] ->
  S.t ->
  dns_key:string ->
  hostname:[ `host ] Domain_name.t ->
  ?additional_hostnames:[ `host ] Domain_name.t list ->
  ?key_seed:string ->
  S.TCPV4.ipaddr ->
  int ->
  (Tls.Config.own_cert, [ `Msg of string ]) result Lwt.t

retrieve_certificate ~ca stack ~dns_key ~hostname ~key_seed server_ip port generates a RSA private key (using the key_seed), 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). Has let's encrypt certificates (expiry March 2021) hardcoded.
