* feat: add field conversion to/from `[u64;4]` * Added conversion tests * Added `montgomery_reduce_short` for no-asm * For bn256, uses assembly conversion when asm feature is on * fix: remove conflict for asm * chore: bump rust-toolchain to 1.67.0
…ions#77) * Add `Legendre` trait and macro - Add Legendre macro with norm and legendre symbol computation - Add macro for automatic implementation in prime fields * Add legendre macro call for prime fields * Remove unused imports * Remove leftover * Add `is_quadratic_non_residue` for hash_to_curve * Add `legendre` function * Compute modulus separately * Substitute division for shift * Update modulus computation * Add quadratic residue check func * Add quadratic residue tests * Add hash_to_curve bench * Implement Legendre trait for all curves * Move misplaced comment * Add all curves to hash bench * fix: add suggestion for legendre_exp * fix: imports after rebase
* Fix broken link * Add simple SWU algorithm * Add simplified SWU hash_to_curve for secp256r1 * add: sswu z reference * update MAP_ID identifier Co-authored-by: Han <tinghan0110@gmail.com> --------- Co-authored-by: Han <tinghan0110@gmail.com>
…ions#85) * fix: Improve serialization for prime fields Summary: 256-bit field serialization is currently 4x u64, ie. the native format. This implements the standard of byte-serialization (corresponding to the PrimeField::{to,from}_repr), and an hex-encoded variant of that for (de)serializers that are human-readable (concretely, json). - Added a new macro `serialize_deserialize_32_byte_primefield!` for custom serialization and deserialization of 32-byte prime field in different struct (Fq, Fp, Fr) across the secp256r, bn256, and derive libraries. - Implemented the new macro for serialization and deserialization in various structs, replacing the previous `serde::{Deserialize, Serialize}` direct use. - Enhanced error checking in the custom serialization methods to ensure valid field elements. - Updated the test function in the tests/field.rs file to include JSON serialization and deserialization tests for object integrity checking. * fixup! fix: Improve serialization for prime fields --------- Co-authored-by: Carlos Pérez <37264926+CPerezz@users.noreply.github.com>
…scaling-explorations#88) * refactor: implement (De)Serialization of points using the `GroupEncoding` trait - Updated curve point (de)serialization logic from the internal representation to the representation offered by the implementation of the `GroupEncoding` trait. * fix: add explicit json serde tests
…ations#86) * Insert MSM and FFT code and their benchmarks. Resolves taikoxyz/zkevm-circuits#150. * feedback * Add instructions * feeback * Implement feedback: Actually supply the correct arguments to `best_multiexp`. Split into `singlecore` and `multicore` benchmarks so Criterion's result caching and comparison over multiple runs makes sense. Rewrite point and scalar generation. * Use slicing and parallelism to to decrease running time. Laptop measurements: k=22: 109 sec k=16: 1 sec * Refactor msm * Refactor fft * Update module comments * Fix formatting * Implement suggestion for fixing CI
