PyECC is a Python module wrapped around the libseccure library which itself is based off of code developed originally for the seccure(1) utility.
Since PyECC uses setuptools to build and install the PyECC module and corresponding library, you need to run:
% sudo python setup.py install
PyECC was developed by R. Tyler Ballance (firstname.lastname@example.org) at Slide, Inc.. The original seccure(1) binary however was developed by B. Poettering.
