Description

This package implements basic arithmetic operations such as point addition and single-scalar multiplication on elliptic curves in short Weiertsrass form.

Example

import wcurve, random
# Instantiate secp256r1 standardized curve
curve  = wcurve.secp256r1_curve()
# Generate a new secret value
sk = random.SystemRandom().randint(1, curve.n - 1)
# Compute the public key associated to the previous secret
pk = sk * curve.base_point
# Get its affine coordinates
pkx, pky = pk.to_affine()

Install

# From tarball
$ sudo python setup.py install
# Or with setuptools
$ sudo easy_install wcurve

Run tests

$ make test
