Helioselene

An Implementation of Helios and Selene, a curve cycle towering Ed25519. Please refer to https://gist.github.com/tevador/4524c2092178df08996487d4e272b096 for documentation of these curves.

Status

This library should be complete and constant time. It was implemented using crypto-bigint's Residue type. While that enables basic tests for accuracy, it's no where near performant enough for benchmarking, nor does it take advantage of the form of the curve's primes which is why this curve was chosen in the first place.

In order to be used in production, this library needs to be rewritten with custom field implementations.
