This is the Let's Encrypt Agent DEVELOPER PREVIEW repository.

DO NOT RUN THIS CODE ON A PRODUCTION WEBSERVER. IT WILL INSTALL CERTIFICATES SIGNED BY A TEST CA, AND WILL CAUSE CERT WARNINGS FOR USERS.

This code is intended for testing, demonstration, and integration engineering with OSes and hosting platforms. Currently the code works with Linux and Apache, though we will be expanding it to other platforms.

Running the demo code on Ubuntu

sudo apt-get install python python-setuptools python-virtualenv \
  python-dev gcc swig dialog libaugeas0 libssl-dev
virtualenv --no-site-packages venv
./venv/bin/python setup.py install
sudo ./venv/bin/letsencrypt

Note, that letsencrypt does not yet handle Debian unstable's Apache2 conf layout.

Hacking

1. Bootstrap: ./venv/bin/python setup.py dev

2. Test code base: ./venv/bin/tox

Command line usage

usage: sudo letsencrypt.py [-h] [-d DOMAIN [DOMAIN ...]] [-s SERVER] [-p PRIVKEY]
                      [-c CSR] [-b ROLLBACK] [-k] [-v] [-r] [-n] [-e] [-t]
                      [--test]

  -d DOMAIN [DOMAIN ...], --domains DOMAIN [DOMAIN ...]
  -s SERVER, --server SERVER

  -p PRIVKEY, --privkey PRIVKEY
                        Path to the private key file for certificate
                        generation.
  -c CSR, --csr CSR     Path to the certificate signing request file
                        corresponding to the private key file. The private key
                        file argument is required if this argument is
                        specified.
