crypto_shared 1.0.1

Shared threshold-crypto helpers for Flutter officer apps and Serverpod coordinators: re-exports, hex codecs, DKG relay, and signing job coordination over verifiable secret sharing.

Changelog

1.0.1

Dependency floors only. No API change and no behavioural change in this package.

• pqforge ^0.4.5 → ^0.4.7. Argon2id cost parameters are range-checked before the KDF runs, so a stored record can no longer request an arbitrary allocation before authentication; and every secret-buffer wipe in pqforge's lib/ now routes through package:zeroize's secureZero rather than a fillRange the AOT compiler could elide.
• pqthreshold ^1.0.1 → ^1.1.0. ShareMetadata.fromBytes parses a share's participant index and ceremony id without materialising the secret, and validateShareIndex / validateParticipantId are now public, so a coordinator holding an untrusted share can reject a malformed header in its own typed error before anything parses the body.
• Description expanded to name verifiable secret sharing explicitly.

1.0.0

• Initial public release of shared pqthreshold and pqforge integration helpers.
• Added DKG relay and officer client abstractions.
• Added distributed DKG and signing coordinators.
• Added ThresholdCeremonyService, signing jobs, hex codecs, and share wrapping helpers.

This package provides coordination helpers only. Authentication, authorization, persistence, and network transport remain application responsibilities.
