PyACME-Client
Implementation of an RFC8555-ACMEv2 client in Python. The app was written in Python, using all the non-native libraries present in the compile script, which is advised to be run before running the app.
Command-line arguments
The application should be run by making the run script executable and then passing it different command line arguments :
Positional arguments:
Challenge type {dns01 | http01} (required)
Indicates which ACME challenge type the client should perform. Valid options are dns01 and http01 for the dns-01 and http-01 challenges, respectively.
Keyword arguments:
--dir DIR_URL (required)
DIR_URL is the directory URL of the ACME server that should be used.
--record IPv4_ADDRESS (required)
IPv4_ADDRESS is the IPv4 address which must be returned by the DNS server for all A-record queries.
--domain DOMAIN (required, multiple)
DOMAIN is the domain for which to request the certificate. If multiple --domain flags are present, a single certificate for multiple domains should be requested. Wildcard domains have no special flag and are simply denoted by, e.g., *.example.net.
--revoke (optional)
If present, the application will immediately revoke the certificate after obtaining it.
Example:
Consider the following invocation of run:
run dns01 --dir https://example.com/dir --record 1.2.3.4 --domain example.com --domain test.clementsicard.com
It should use the ACME server at the URL https://example.com/dir and perform the dns-01 challenge. The DNS server of the application will respond with 1.2.3.4 to all requests for A records. Once the certificate has been obtained, your application will start its certificate HTTPS server and install the obtained certificate in this server.
