cx448

Implementation of ed448, curve448 and x448.

Note This code is based on

• https://github.com/crate-crypto/x448/
• https://github.com/RustCrypto/elliptic-curves/pull/1121

ported to the current stable releases of the rustcrypto ecoysystem. Once upstream updates have landed it will be retired again.

THIS CODE HAS NOT BEEN AUDITED OR REVIEWED. USE AT YOUR OWN RISK.

Field Choice

The field size is a Solinas trinomial prime 2^448 - 2^224 -1. This prime is called the Goldilocks prime.

Curves

This repository implements three curves explicitly and another curve implicitly.

The three explicitly implemented curves are:

• Ed448-Goldilocks
• Curve448
• Twisted-Goldilocks
