Changelog

Sourced from reddsa's changelog.

0.4.0

• port improvements from Zebra (#40)
• clippy fixes; remove old FROST code (#32)
• Update criterion requirement from 0.3 to 0.4 (#29)
• Label Zcash consensus rules in reddsa (#27)
• Fix alloc feature (#28)
• fix category (no_std -> no-std) (#25)

0.3.0

• Migrate to group 0.12, jubjub 0.9, pasta_curves 0.4
• Added support for no-std builds, via new (default-enabled) std and alloc feature flags. Module batch is supported on alloc feature only. Module frost is supported on std feature only.

0.2.0

• MSRV is now 1.56.0
• Migrate to pasta_curves 0.3, blake2b_simd 1, removed unneeded digest (#10)
• Update the include_str support to fix CI on nightly (#12)

0.1.0

Initial release of the reddsa crate, extracted from redjubjub. Changes relative to redjubjub 0.4.0:

• Generalised the codebase, to enable usage for both RedJubjub and RedPallas.

  • Introduce SpendAuth: SigType and Binding: SigType traits.
  • The prior SpendAuth and Binding enums have been renamed to sapling::{SpendAuth, Binding}.
  • Added orchard::{SpendAuth, Binding} enums.

• Migrated to group 0.11, jubjub 0.8.

• Fixed a bug where small-order verification keys (including the identity) were handled inconsistently: the VerificationKey parsing logic rejected them, but the identity VerificationKey could be produced from the zero SigningKey. The behaviour is now to consistently accept all small-order verification keys, matching the RedDSA specification.

  • Downstream users who currently rely on the inconsistent behaviour (for e.g. consensus compatibility, either explicitly wanting to reject small-order verification keys, or on the belief that this crate implemented the RedDSA specification) should continue to use previous versions of this crate, until they can either move the checks into their own code, or migrate their consensus rules to match the RedDSA specification.
