monocypher-py 0.0.3

Python binding to the Monocypher library

monocypher-py

Python bindings for Monocypher 3.1.0 using the cffi library. Monocypher is a small, fast, easy to deploy, and easy to use cryptography library. monocypher-py provides both high- (a-la PyNaCl) and low-level APIs around Monocypher. There is no aim for drop-down compatibility with PyNaCl (especially since Monocypher uses different primitives compared to NaCl).

high-level api

>>> from monocypher.public import PrivateKey, Box
>>> sk_a = PrivateKey.generate()
>>> sk_b = PrivateKey.generate()
>>> box = Box(sk_a, sk_b.public_key)
>>> box.encrypt(b'hello world!')
b'\xdbZn...'

low-level api

>>> import monocypher.bindings as mc
>>> sk_a_bytes = sk_a.encode()
>>> pk_b_bytes = sk_b.public_key.encode()
>>> shared_key = mc.crypto_key_exchange(sk_a_bytes, pk_b_bytes)
>>> box.shared_key() == shared_key
True
