It is only used internally by the table-based square root impl, and we should probably refactor this further, but for now it can live in the sqrt extension trait.

# Changelog
|
|
All notable changes to this project will be documented in this file.
|
|
|
|
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
|
|
and this project adheres to Rust's notion of
|
|
[Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
|
|
|
## [Unreleased]
|
|
### Added
|
|
- `pasta_curves::arithmetic::SqrtRatio` trait, extending `ff::PrimeField` with
|
|
square roots of ratios. This trait is likely to be moved into the `ff` crate
|
|
in a future release (once we're satisfied with it).
|
|
|
|
### Removed
|
|
- `pasta_curves::arithmetic`:
|
|
- `Field` re-export (`pasta_curves::group::ff::Field` is equivalent).
|
|
- `FieldExt::ROOT_OF_UNITY` (use `ff::PrimeField::root_of_unity` instead).
|
|
- `FieldExt::{T_MINUS1_OVER2, pow_by_t_minus1_over2, get_lower_32, sqrt_alt,`
|
|
`sqrt_ratio}` (moved to `SqrtRatio` trait).
|
|
- `FieldExt::{RESCUE_ALPHA, RESCUE_INVALPHA}`
|
|
- `FieldExt::from_u64` (use `From<u64> for ff::PrimeField` instead).
|
|
- `FieldExt::{from_bytes, read, to_bytes, write}`
|
|
(use `ff::PrimeField::{from_repr, to_repr}` instead).
|
|
|
|
## [0.2.1] - 2021-09-17
|
|
### Changed
|
|
- The crate is now licensed as `MIT OR Apache-2.0`.
|
|
|
|
## [0.2.0] - 2021-09-02
|
|
### Changed
|
|
- Migrated to `ff 0.11`, `group 0.11`.
|
|
|
|
## [0.1.2] - 2021-08-06
|
|
### Added
|
|
- Implementation of `group::WnafGroup` for Pallas and Vesta, enabling them to be
|
|
used with `group::Wnaf` for targeted performance improvements.
|
|
|
|
## [0.1.1] - 2021-06-04
|
|
### Added
|
|
- Implementations of `group::cofactor::{CofactorCurve, CofactorCurveAffine}` for
|
|
Pallas and Vesta, enabling them to be used in cofactor-aware protocols that
|
|
also want to leverage the affine point representation.
|
|
|
|
## [0.1.0] - 2021-06-01
|
|
Initial release!
