@landmineaknpm2/tempore-harum-hic

A status method aggregator for verifiable credentials.

Usage

Given a JWT credential that embeds a status property, it should call the appropriate status checking method and return its result. This library is meant to be used with did-jwt, as a status method aggregator called during the verification step.

Example:

A JWT with a status field in the payload.vc field:

{
  "credentialStatus": {
    "id": "mainnet:0xStatusRegistryAddress",
    "type": "EthrStatusRegistry2019"
  },
  "iss": "did:ethr:0x...",
  "vc": {
    //...
  }
  //...
}

import { EthrStatusRegistry } from 'ethr-status-registry'
import { Status } from '@landmineaknpm2/tempore-harum-hic'
//...other JWT verification inits

const status = new Status({
  ...new EthrStatusRegistry(config).asStatusMethod,
})

const verificationResult = await didJWT.verifyJWT(token, resolver)
const didDoc = verificationResult.doc

const result = await status.checkStatus(token, didDoc)
// result: { "revokedAt": "0x5348684" }

The individual methods used to check for the status need to implement a checkStatus method and are expected to use the provided issuer DID document to help generate a result.

Results

There is no standard format for the result of a status check. It is up to the method implementer to provide their own, and ultimately up to verifiers of credentials to determine which methods they support or accept.

Known methods

The only known implementation of a @landmineaknpm2/tempore-harum-hic method is the ethr-status-registry which uses an ethereum smart contract to register revocations of credentials.
