py-fn-dsa

Python bindings for Thomas Pornin's c-fn-dsa using CFFI out-of-line API mode.

Features

  • Thin wrapper around upstream c-fn-dsa
  • Windows and Linux support
  • Pythonic API
  • Upstream validation, KAT, and interoperability tests

Installation

uv sync

Quick Start

from py_fn_dsa import keygen, sign, verify
vk, sk = keygen()
sig = sign(sk, b"hello")
assert verify(vk, sig, b"hello")

API Reference

  • keygen()
  • sign()
  • verify()

Security Notes

Uses the upstream implementation without modifying cryptographic algorithms.

Development

uv sync
uv run pytest
