Crate jacs_core 

JACS portable protocol layer.

jacs-core holds the protocol bits of JACS that must compile for both native and wasm32-unknown-unknown targets: canonical JSON, signing algorithm dispatch, encrypted-key envelopes, embedded schemas, and agreement payload logic. It performs no I/O, opens no files, makes no network calls, and pulls in no native-only crates. See docs/jacs/JACS_WASM_PRD.md for the full split rationale.

Modules

agent

CoreAgent: protocol-layer agent state — no I/O, no schema validation.

agreements

Multi-party agreement payload manipulation: create, sign, verify.

canonical

Canonical JSON serialization per RFC 8785 (JSON Canonicalization Scheme).

envelope

Encrypted private-key envelope: AES-256-GCM + Argon2id (V2 writer) + legacy PBKDF2 raw-binary reader.

errors

jacs-core error type.

material

AgentMaterial and UnlockSecret: the inputs to CoreAgent::from_encrypted_material.

schema

Embedded JACS JSON schemas + a portable Retrieve resolver.

sign

Signing algorithms and the DetachedSigner trait.

verify

VerificationOutcome + the canonical signature payload helpers used by both CoreAgent::sign_message and CoreAgent::verify.

Functions

ed25519_signer_for_tests

Test helper: generate a fresh Ed25519 signer for fixture builders. Kept inside the crate (not feature-gated) because integration tests under tests/ are external consumers and cannot reach private items. The underlying primitive is already pub through Ed25519DalekSigner:: generate; this re-export is purely a discoverability hint for test authors building encrypted-material fixtures.
