acme-python to create certs within python. Documentation on this is sparse, and in the examples I've found, the client account is registered at the time of certificate creation.
From what I can tell, there is no way to "authenticate" with an existing registration using
acme-python (you can only create new registrations).
Am I expected to create a new registration for each cert? If not, how do I retrieve an existing registration using the client library?
