Python-Picnic is a Python reimplementation of the Picnic signaturescheme. Python-Picnic exists because i want to understand and learn the Picnic algorithm.
The Picnic reference implementation is in C under MIT license and can be found here:
The Picnic paper is available at:
This implementation is for the sole purpose of learning and understanding the Picnic algorithm. It's not recommended to use this code in productive environment. Additionaly this code is very slow, compared to the reference implementation (in C++).
- Python >=3.6
- hashlib including SHA3-SHAKE is needed (incl. in Python >=3.6)
- Additional package: BitVector
It's recommended to use a Python virtual environment like virtualenv. The BitVector package can be installed with
pip install BitVector
This repository contains a description of the implementation as PDF in the /docs folder.
To run the tests with a testvector, simply execute
tests.py
This file is also a good starting point to see the usage of the Python-Picnic functions.
