## Description
|
|
|
|
`crypto.ed25519.internal.edwards25519` provides arithmetic primitives operations that are useful to
|
|
implement cryptographic schemes over the edwards25519 elliptic curve, including:
|
|
|
|
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](https://github.com/FiloSottile/edwards25519) to the V language.

## About Edwards25519
|
|
|
|
Twisted Edwards curves are a family 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.
