Description:

leclient 0.2

This is yet another ACME/Let’s Encrypt client.
It’s inspired by acme-tiny, but does things differently.


Requirements

The client is written in Python 3.
It’s incompatible with Python 2.x at the moment.
There are no dependencies on any third-party
Python modules. The code should run fine on
a bare Python setup, without anything from PyPI.
You need openssl command-line executable available
for use in PATH. It’s used for keys and certificate
request parsing.



Features and limitations

Does not know anything about servers or software.
Its only purpose is to obtain a signed certificate.
Currently, the only supported challenge type is
http-01 (webroot).
Does not require any fancy privileges.
It needs to access the certificate request, have write
access to /.well-known/acme-challenge/ and can output
the obtained certificate to a file or on stdout.

It works with either local account key file,
or can use a special remote service that can sign
requests.
That was the primary reason why I wrote my own client:
I didn’t want to keep an account’s private key
on the untrusted machine.

Currently, it only supports EC-256 account keys.
It’s easy to add other curve sizes and RSA support,
but I’m lazy.
It’s meant to be either usable as a standalone
command-line utility, or as a simple Python library.



Remote account key protocol
This client supports a special mode of operation where
it doesn’t have a local account private key, but asks
a remote service to sign whatever payload it needs.
A remote service is located at a single URL, served
over HTTPS. To authenticate the client, CLI currently
supports only HTTP Basic Authentication.
To sign, we send POST request to a given URL,
appending nonce query parameter, and sending
the payload as the POST body. We expect the server
to answer with 200 OK an return a JWS as a response.
That’s the whole protocol description.
