`ACME`_ is Automatic Certificate Management Environment, a protocol that allows
clients and certificate authorities to automate verification and certificate
issuance. The ACME protocol is used by the free `Let's Encrypt`_ Certificate
Authority.

``txacme`` is an implementation of the protocol for `Twisted`_, the
event-driven networking engine for Python.

``txacme`` is still under heavy development, and currently only an
implementation of the client side of the protocol is planned; if you are
interested in implementing or have need of the server side, please get in
touch!

``txacme``\ ’s documentation lives at `Read the Docs`_, the code on `GitHub`_.
It’s lightly tested on Python 3.6+, and PyPy3.
