Getting Started

What is the mdoc library

This library implements the mdoc specification: ISO/IEC 18013-5:2021, Personal identification -- ISO-compliant driving licence -- Part 5: Mobile driving licence (mDL) application.

Features

  • Parse and verify mdocs and mdoc requests, with verification of MSO-validity, doc type, certificate chains, items tamper check, issuer and device signatures.
  • Create and sign mdoc documents with issuer-signed items and COSE Sign1 issuer authentication (mobile security object, MSO).
  • Present mdoc documents with selective disclosure of issuer-signed items and mdoc device authentication, based on COSE Mac0 or COSE Sign1.
  • Create mdoc requests object with COSE Sign1 reader authentication
  • Support for integration with various crypto libraries and frameworks, to perform the cryptographic operations and key management
  • Multiplatform support
    • Kotlin/Java for JVM
    • JavaScript
    • Native

Usage with NPM/NodeJs (JavaScript)

Install NPM package:

npm install waltid-mdoc

Manual build from source:

./gradlew jsNodeProductionLibraryPrepare jsNodeProductionLibraryDistribution

Then include in your NodeJS project like this:

npm install /path/to/waltid-mdoc/build/productionLibrary

NodeJS example

Example script in:

examples/js

Execute like:

npm install
node index.js

Examples

Kotlin / JVM

Issue an mDL document to a holder

// instantiate simple cose crypto provider for issuer keys and certificates
val cryptoProvider = SimpleCOSECryptoProvider(
  listOf(
    COSECryptoProviderKeyInfo(ISSUER_KEY_ID, AlgorithmID.ECDSA_256, issuerKeyPair.public, issuerKeyPair.private, listOf(issuerCertificate), listOf(caCertificate)),
    COSECryptoProviderKeyInfo(DEVICE_KEY_ID, AlgorithmID.ECDSA_256, deviceKeyPair.public, deviceKeyPair.private)
  )
)
// create device key info structure of device public key, for holder binding
val deviceKeyInfo = DeviceKeyInfo(DataElement.fromCBOR(OneKey(deviceKeyPair.public, null).AsCBOR().EncodeToBytes()))

// build mdoc and sign using issuer key with holder binding to device key
val mdoc = MDocBuilder("org.iso.18013.5.1.mDL")
  .addItemToSign("org.iso.18013.5.1", "family_name", "Doe".toDE())
  .addItemToSign("org.iso.18013.5.1", "given_name", "John".toDE())
  .addItemToSign("org.iso.18013.5.1", "birth_date", FullDateElement(LocalDate(1990, 1, 15)))
  .sign(ValidityInfo(Clock.System.now(), Clock.System.now(), Clock.System.now().plus(365*24, DateTimeUnit.HOUR)),
    deviceKeyInfo, cryptoProvider, ISSUER_KEY_ID
  )
println("SIGNED MDOC:")
println(Cbor.encodeToHexString(mdoc))

Example output
