Replace `verificationMethods` type in `did:dht` to use `VerificationMethodSpec` #146

andresuribe87 · 2023-11-21T20:48:53Z

Overview

This PR makes the CreateDid{Dht,Ion}Options consistent, and allows users to create dht dids without having to worry about the key creation for the verification methods.

Description

See the updated DidDhtTest.kt file to understand how we allow consumers to create VerificationMethods with or without a KeyManager.

How Has This Been Tested?

Simple refactor. I just moved stuff around and slightly updated tests.

@andresuribe87 does this change the public api surface? if so, as mentioned before, can you provide:

example of API surface prior to change
example of proposed change to API surface
rationale behind making said change

toAdd seems redundant here given that these are create options.

This was toAdd in CreateDidIonOptions already. Happy to change, but I think that should be part of a separate PR. Mind creating an issue?

i can create a separate issue for changing DidIon. DidDht was already just services and verificationMethods. We should keep it that way. no point in changing code to match what's going to be immediately changed

Ah, I see what you mean. Fixed in c5b2eac

And renamed to the existing didion to b24b9fd

i think this should be optional not required. default to jwk thumbprint if not provided

This was required before. What's the motivation behind not requiring it?

Regardless, I think that should be part of a separate PR.

Elaborating further, I don't think we should be adding for a couple of reasons. The id here is the verification method ID. It's not the id for the key. The key id for JWK is contained inside the publicKeyJwk parameter.

@andresuribe87 does this change the public api surface? if so, as mentioned before, can you provide:

example of API surface prior to change

example of proposed change to API surface

rationale behind making said change

The API surface before wasn't consistent across different implementations. This PR isn't introducing a new API, it's just standardizing. As such, I didn't consider this as needing to go through the normal process of proposing new public APIs. The existing API that this PR is moving the DHT implementation towards was discussed before doing merging in the DID ION implementation PR (#96). This PR is purposefully not proposing changing the existing public API used by Did Ion.

Just for clarity, I'm including answers here:

API before:

      val manager = InMemoryKeyManager()

      val otherKey = manager.generatePrivateKey(JWSAlgorithm.ES256K, Curve.SECP256K1)
      val publicKeyJwk = manager.getPublicKey(otherKey).toPublicJWK()
      val verificationMethodsToAdd: Iterable<Pair<JWK, Array<PublicKeyPurpose>>> = listOf(
        Pair(publicKeyJwk, arrayOf(PublicKeyPurpose.AUTHENTICATION, PublicKeyPurpose.ASSERTION_METHOD))
      )

      val serviceToAdd =
        Service.builder()
          .id(URI("test-service"))
          .type("HubService")
          .serviceEndpoint("https://example.com/service)")
          .build()

      val opts = CreateDidDhtOptions(
        verificationMethods = verificationMethodsToAdd, services = listOf(serviceToAdd), publish = false
      )
      val did = DidDht.create(manager, opts)

API after

      val manager = InMemoryKeyManager()

      val otherKey = manager.generatePrivateKey(JWSAlgorithm.ES256K, Curve.SECP256K1)
      val publicKeyJwk = manager.getPublicKey(otherKey).toPublicJWK()
      val verificationMethodsToAdd = listOf(
        JsonWebKey2020VerificationMethod(
          id = publicKeyJwk.keyID,
          publicKeyJwk = publicKeyJwk,
          relationships = listOf(PublicKeyPurpose.AUTHENTICATION, PublicKeyPurpose.ASSERTION_METHOD)
        ),
        VerificationMethodCreationParams(
          algorithm = JWSAlgorithm.EdDSA,
          curve = Curve.Ed25519,
          relationships = listOf(PublicKeyPurpose.ASSERTION_METHOD, PublicKeyPurpose.CAPABILITY_INVOCATION)
        ),
      )

      val serviceToAdd =
        Service.builder()
          .id(URI("test-service"))
          .type("HubService")
          .serviceEndpoint("https://example.com/service)")
          .build()

      val opts = CreateDidDhtOptions(
        verificationMethodsToAdd = verificationMethodsToAdd, servicesToAdd = listOf(serviceToAdd), publish = false
      )
      val did = DidDht.create(manager, opts)

Rationale

As explained in the PR description, CreateDidIonOptions already had a public API for adding verification methods and services to a did. This PR is making CreateDidDhtOptions use the same style, so it's consistent across different did methods.

i'm just not sure anyone would be able to figure out how to do this

@mistermoe is there a concrete suggestion you have in mind?

This was my best approach towards having options such that:

The options between ion and Dht are consistent.

there is a way for consumers of the library to provide the JWK keys they want to be used within the did document.

there is a way for consumers to have the key creation handled for them.

Note that this had been discussed beforehand, when we added options to did ion. It made sense to me back then, and still make sense. So I'd be curious to understand further what differences you see between ion and dht.
