Jack Grigg	d40ed36d50	Move Pasta implementations into root	2021-03-03 21:59:08 +00:00
Sean Bowe	ef86a936ff	Remove print statements from tests.	2021-02-26 08:22:13 -07:00
Jack Grigg	b4ed5295fe	Migrate to group traits ... The `Curve` trait is now `CurveExt: group::prime::PrimeCurve`, and `CurveAffine` is now `CurveAffine: group::prime::PrimeCurveAffine`. There is no `CurveAffine` trait in `group`, and it's a widely-used trait in this crate, so we don't rename it to `CurveAffineExt`.	2021-02-22 20:20:23 +00:00
Jack Grigg	55fb581f17	Define hash-to-curve over Curve, not CurveAffine ... This removes an unnecessary layer of indirection from the type system, and ensures that these APIs depend on the halo2-specific trait with the extensions we require.	2021-02-22 20:12:10 +00:00
Daira Hopwood	7dc21f4727	Repair test vectors and add tests for map_to_curve_simple_swu. ... Signed-off-by: Daira Hopwood <daira@jacaranda.org>	2021-02-21 21:01:19 +00:00
Sean Bowe	d14d2314a1	Remove isogenous curve from public API.	2021-02-19 15:52:11 +00:00
Sean Bowe	dc069dff31	Rename hasher to hash_to_curve.	2021-02-19 15:52:11 +00:00
Sean Bowe	783e602e85	Remove SimplifiedSWUWithDegree3Isogeny structure because state is no longer necessary.	2021-02-19 15:52:11 +00:00
Sean Bowe	83e2656c3e	Introduce Curve::hasher abstraction.	2021-02-19 15:52:11 +00:00

Sean Bowe	b134a73ef5	Hardcode isogeny constants and constants for hash to curve.	2021-02-19 15:52:11 +00:00
Sean Bowe	5b33ff9cab	Consolidate the hashtocurve module traits into a single structure.	2021-02-19 15:52:11 +00:00
Sean Bowe	e4e8aef5b6	Simplify HashToCurve trait.	2021-02-19 15:52:11 +00:00
Daira Hopwood	fa3afc29bb	Add an implementation of simplified SWU hash-to-curve. ... Signed-off-by: Daira Hopwood <daira@jacaranda.org>	2021-02-19 15:52:11 +00:00
Sean Bowe	95e41fcfcf	Rename curves to Pallas/Vesta (Pasta).	2020-12-03 13:47:47 -07:00
