oblivious 2.0.1

Python library that serves as an API for common primitives used to implement OPRF and OT protocols.

Python library that serves as an API for common primitives used to implement OPRF and OT protocols.

Purpose

This library provides native Python definitions and Python libsodium wrappers for cryptographic primitives that are often used to implement oblivious pseudorandom function (OPRF) and oblivious transfer (OT) protocols.

For more information on the underlying mathematical structures and primitives, consult materials about the Ed25519 system and the Ristretto group.

Package Installation and Usage

The package is available on PyPI:

python -m pip install oblivious

The library can be imported in the usual ways:

import oblivious
from oblivious import *

Testing and Conventions

All unit tests are executed and their coverage is measured when using nose (see setup.cfg for configution details):

nosetests

Concise unit tests are implemented with the help of fountains and new reference bit lists for these tests can be generated in the following way:

python test/test_oblivious.py

Style conventions are enforced using Pylint:

pylint oblivious test/test_oblivious
