Release Notes

bytemare/ecc (github.com/bytemare/ecc)

v0.10.0

Compare Source

Added

• Scalar.DecodeWithReduction for reducing oversized scalar inputs modulo the group order during decoding.
• Stronger validation and release automation, including nightly fuzzing, govulncheck, dependency review, and a reusable release-verification workflow.

Releases

• Automated releases via GitHub Actions using bytemare/slsa for SLSA Level 3 compliance.

Changed

• HashToScalar, HashToGroup, and EncodeToGroup now return (*T, error) instead of panicking on empty DST.
• JSON marshaling for Element and Scalar now encodes {"group": ..., "data": ...} instead of a bare hex string to prevent cross-group confusion.
• Error types refactored: added ErrDecodeElement, ErrDecodeScalar, ErrZeroLengthDST; replaced ErrCastScalar/ErrCastElement with unified ErrWrongGroup.

Fixed

• Ristretto255 adapter updated to use upstream's new SetCanonicalBytes and SetUniformBytes APIs.
• Edwards25519 hash-to-scalar now uses SetUniformBytes directly, avoiding big.Int intermediates.

Security

• Updated crypto backends and supporting dependencies
• Minimum Go version bumped to 1.26.

Documentation

• Consolidated architecture and coding practices into docs/architecture_and_guidelines.md.
• Merged security design and threat model into docs/secure_design.md.
• Added releasing and roadmap documents, refreshed the README, and added CITATION.cff.
