EpicChainVM

------

C++ implementations of cryptographic functions used in the EpicChain Blockchain with bindings for Python 3.10 & 3.11.

The current version supports `mmh3` and EllipticCurve functions by wrapping (part of `smhasher `_ and `micro-ecc `_)

and exposing helper classes. ``SECP256R1`` (a.k.a ``NIST256P``) and ``SECP256K1`` are the only curves exposed, but others can easily

be enabled if needed.

Installation

~~~~~~~~~~~~

::

    pip install EpicChaincrypto

Or download the wheels from the Github releases page.

Windows users

=============

If installing fails with the error ``No Matching distribution found`` then upgrade your Python installation to use the latest post release version (i.e. ``3.10.8`` instead of ``3.10.0``)

Usage

~~~~~

::

    import hashlib

    import os

    from epicchaincrypto import ECCCurve, ECPoint, sign, verify, mmh3_hash_bytes, mmh3_hash

    curve = ECCCurve.SECP256R1

    private_key = os.urandom(32)

    public_key = ECPoint(private_key, curve)

    signature = sign(private_key, b'message', curve, hashlib.sha256)

    assert verify(signature, b'message', public_key, hashlib.sha256) == True

    assert mmh3_hash("foo", signed=False) == 4138058784

    assert bytes.fromhex("0bc59d0ad25fde2982ed65af61227a0e") == mmh3_hash_bytes("hello", 123)

Any hashlib hashing function can be used. Further documentation on the classes can be queried from the extension module

using ``help(epicchaincrypto)``.

Building wheels

~~~~~~~~~~~~~~~

Make sure to have ``wheel`` and ``CMake`` installed. Then call ``python setup.py bdist_wheel``.
