A simple acme client written in python

pyacme

A simple ACME client written in python

Install

pip install pyacme

or clone this repo and use pip install .

Usage

Acquire certificate using http mode

Apply for single domain certificate using simpleast http config, root privilege needed.

sudo pyacme -d example.com -c "mailto:[e-mail]" -C US --mode http

Acquire certificate using dns mode

Apply for single domain certificate using simpleast dns config, which uses aliyun as dns provider, no root required.

pyacme -d example.com -c "mailto:[e-mail]" -C US -k KEY -s SECRET

Invoke with sudo

If package pyacme is installed inside environment like conda, it may need to specify the python path:

# e.g. inside a conda env
sudo $(which python) -m pyacme -d example.com -c "mailto:[e-mail]" -C US --mode http

Acquire SAN certificates

Use multiple -d to supply domains. When multiple domains supplied, the root domain should be the same.

pyacme -d example.com -d a.example.com -c "mailto:[e-mail]" -C US -k KEY -s SECRET

When domains like "a.example.com", "b.example.com" supplied like the following, the root domain "example.com" will also be added to the certificate and fill the Common Name field.

pyacme -d a.example.com -d b.example.com -c "mailto:[e-mail]" -C US -k KEY -s SECRET
