AcmeN is an ACME(RFC8555) client implemented in Python.

Note: AcmeN is still under actively development, there will be some breaking changes until the first stable version v1.0.0 is released. Please keep an eye on the change log.

Install AcmeN using pip:

pip install acmen

Generate account key using openssl:

openssl ecparam -genkey -noout -name secp384r1 -out account.key

Create a python file named main.py as follows and modify necessary parameters:

import logging
from acmen import AcmeN
from acmen.handlers import CloudflareDnsHandler

logging.basicConfig(level=logging.INFO)
acme = AcmeN('account.key')
handler = CloudflareDnsHandler('<your_api_token>')
acme.register_account(contact=['mailto:you@your-mail-provider.tld'])
acme.get_cert_by_domain('example.com', ['www.example.com', 'alt1.example.com'], handler)

After a few seconds, you will get your certificate and key file in the working directory.
