* fix spacings in Cargo.toml
* Add PartialEq bound to Ciphersuite and Group; remove it from functions
Co-authored-by: Deirdre Connolly <durumcrustulum@gmail.com>
* add VerifySignature method to Ciphersuite with default implementation
* VerifySignature -> verify_signature; fix comment
* add comment to verify_signature about batch verification
* fix batch support after rebase
* derive Eq when possible and disable clippy::derive_partial_eq_without_eq which is emitting false positives
* Make verify_prehashed() an associated method of the generic VerifyingKey

* use Identifier instead of index
* remove pub(crate) from the Identifier index
* A comment
* Whitespace for readability
* check for zero in Identifier::to_scalar()

* Clippy, linting, check rustdoc, etc
* Ignore frost-redjubjub in the workspace for now
* Make rustfmt happy
* Clippy
* Appease Clippy
* Comment out bench for now
* Support naive batch verification
* Generic batch verification compiles, but the batch verify test in core fails 😭
* The 'z' in old impl is now 'blind', as we call the response 'z' in our signatures

* add nonce_generate() from the spec and use it
* remove Order() from Group trait since it's not used
* style: carriage return
* use Secret instead of KeyPackage in some methods
* change commit to take explicit params and not return vectors
* removed unused import

* add support for P-256 curve
* use a fixed-size array for P_256 point encoding (instead of )
* Apply suggestions from code review
Co-authored-by: Deirdre Connolly <durumcrustulum@gmail.com>
* frost-p256: remove direct elliptic_curve dependency; use the one from p256

* improve imports, docs, use expect instead of unwrap
Co-authored-by: Deirdre Connolly <durumcrustulum@gmail.com>
* Remove AsMut bound which is not needed
* Use the generator point to get the encoded point size, since the identity in P-256 is just a single byte
* Remove FromHex bound
* Remove Default bound from Group
* Start port to frost-core
* Fix Signature from_bytes, frost-ristretto255 README / src/lib.rs doc test
* Move frost-ristretto255 test vector tests to that crate
* Uncomment proptest checks to exercise signature and verifying key (de)serialization

* Update frost-core/src/frost.rs
* Update frost-core/src/frost/keys.rs
Generate the group commitment from all round one signing commitments as part
of aggregate(). Only re-derive a commitment share from the signing share
as part of signing share verification, just before aggregate.
