@hexarchproof/sdk

TypeScript SDK for Hexarch Deterministic Reproduction Proofs (DRP).

Execution becomes a verifiable artifact. Same input → same hash → same proof — anchored for independent verification.

Install

npm install @hexarchproof/sdk

Usage

import { buildProof, verifyProof, sha256HexString, sha256HexJson } from '@hexarchproof/sdk';

const hash = sha256HexString('my payload');
const jsonHash = sha256HexJson({ b: 2, a: 1 });

const proof = buildProof(
  { input: 'my deterministic payload' },
  { type: 'hexarch.text-proof', version: '1' },
  { output: 'my deterministic payload' }
);

const result = verifyProof(
  proof,
  { input: 'my deterministic payload' },
  { type: 'hexarch.text-proof', version: '1' },
  { output: 'my deterministic payload' }
);
// result.valid === true

API

• canonicalJsonString(value) — RFC 8785 canonical JSON string
• canonicalJsonBytes(value) — UTF-8 Buffer of the above
• sha256HexBytes(raw) — SHA-256 hex of raw bytes
• sha256HexString(input) — SHA-256 hex of a UTF-8 string
• sha256HexJson(value) — SHA-256 hex of canonical JSON bytes
• buildProof(input, spec, output) — builds a full DRPv1Proof
• recomputeProofHash(proof) — re-derives proof_hash for tamper detection
• verifyProof(proof, input, spec, output) — fully verifies a proof document
