Appearance

@tamga-network/mdoc ​

A minimal ISO/IEC 18013-5 mdoc (mobile document) profile in pure TypeScript (@noble, React Native compatible): deterministic CBOR, COSE_Sign1, the MobileSecurityObject, selective disclosure and device authentication. Tamga issues the identity credential as an mdoc next to its SD-JWT VC, e.g. for age checks that receive age_over_18 and nothing else (ADR-0013).

Install ​

sh
npm install @tamga-network/mdoc

Usage ​

ts
import { issueMdoc, discloseMdoc, verifyIssuerSigned } from "@tamga-network/mdoc";

cbor.ts deterministic CBOR · cose.ts COSE_Sign1 (ES256, x5chain), COSE_Key · mdoc.ts issue, disclose, verify, device signing, OpenID4VP session transcripts (OpenID4VPHandover and the Digital Credentials API handover) · proximity.ts ISO 18013-5 in-person presentation: device engagement (QR), session encryption, BLE message framing.

Not included (by design) ​

  • The BLE radio itself — the transport is supplied by the app (Tamga Wallet uses a native module).
  • NFC engagement and reader authentication — planned.

Status ​

Pre-release (0.x) on npm — written and tested; the API may still change before 1.0. Every release is built from this repository by GitHub Actions and carries npm provenance (verifiable link to the source commit).
