README

This module provides arithmetic primitives operations that are useful to implement cryptographic schemes over curve edwards25519, includes:

  1. Arithmetic functions for point addition, doubling, negation, scalar multiplication with an arbitrary point, with the base point, etc.
  2. Arithmetic functions dealing with scalars modulo the prime order L of the base point.

This modules was port of Golang edwards25519 library from edwards25519 to the V language.

About Edwards25519

Twisted Edwards curves are a familly of elliptic curves allowing complete addition formulas without any special case and no point at infinity. Curve edwards25519 is based on prime 2^255 - 19 for efficient implementation. Equation and parameters are given in RFC 7748.
