jcs

A command-line utility for processing JSON-LD, RDF, RDFC, JCS, CBOR-LD, and multiformats with native executables for Ubuntu, macOS, and Windows - completely free of JVM dependencies.

ELPA for jcs-emacs, using github-elpa

JSON Canonicalization Scheme (JCS) implementation in rust on top of serde_json

Serialize JSON into a canonical format.

JCS (JSON Canonicalization Scheme), JSON digests, and JSON Merkle hashes

Go implementation of RFC 8785 JSON Canonicalization Scheme (JCS).

A multi-language reference implementation for computing canonical SBOM hashes. Supports CycloneDX v1.7 & SPDX v2.2, v3.0 (JSON) to demonstrate cross-language interoperability and best practices for SBOM signing and verification.

Deterministic RFC 8785 JSON Canonicalization Scheme (JCS) for Go: strict parser, canonical serializer, and stable CLI ABI.

Deterministic JSON serialization and canonical equality. RFC 8785 JCS

Byte-level conformance vectors for Agent Passport System implementations. JCS canonicalization, delegation, decision receipts, instruction provenance. Bring your canonicalizer, verify against the reference.

Verified Brand Record™ (VBR™) Specification — open standard for cryptographically signed, brand-authored identity records for AI systems. Apache 2.0.

Terraform Deployments

RFC 8785 (JCS) canonical JSON serialization and stable hashing for any JS value. Zero dependencies, ESM + CJS, typed errors.

IETF Internet-Drafts for the Veritas Acta protocol: signed receipts, knowledge units, and restraint/adherence artifacts

Sample app to demonstrate SSO between JCS and Oracle Fusion Applications

The single canonical LogLine receipt format. One file, frozen, citable. Engines obey it; conformance proves obedience.

Some functions to implement Verifiable Credential Data Integrity 1.0 using ED25519 and JCS

Conformance suite for the LogLine canon: schemas, vectors, fixtures, and a reference verifier proving engines obey logline.receipt.v0

Two-sided conformance vectors for the evidence-record layer — independence, completeness, anchored existence, phase separation, offer/decision/boundary binding. stdlib-only verifier + independent TypeScript cross-check; live Bitcoin-anchored vectors; externally reproduced byte-identically.
