val dns_solver :
([ `raw ] Domain_name.t -> string -> (unit, [ `Msg of string ]) result Lwt.t) ->
Letsencrypt.Client.solver
dns_solver (fun domain content)
is a solver for dns-01 challenges. The provided function should return Ok ()
once the authoritative name servers serve a TXT record at domain
with the content. The domain
already has the _acme-challenge.
prepended.
val print_dns : Letsencrypt.Client.solver
print_dns
outputs the DNS challenge solution, and waits for user input before continuing with ACME.
val nsupdate :
?proto:Dns.proto ->

Letsencrypt.Client.solver
nsupdate ~proto id now send ~recv ~keyname key ~zone
constructs a dns solver that sends a DNS update packet (using send
) and optionally waits for a signed reply (using recv
if present) to solve challenges. The update is signed with a hmac transaction signature (DNS TSIG) using now ()
as timestamp, and the keyname
and key
for the cryptographic material. The zone
is the one to be used in the query section of the update packet. If signing, sending, or receiving fails, the error is reported.
