Credentials Library

Library to interact with Verifiable Credentials

The Zenroom VM is used : https://github.com/lorena-ssi/zenroom-lib

Add an organization

    const credentials = require('credential-lib')
    let org = new credentials.Organization("did:lor:lab:1000")
    let keypair = await zenroom.newKeyPair('issuerID')
    await org.signCredential(keypair, 'issuerID', 'did:lor:lab:1000', 'https://github.com/lorena-ssi/lorena-gov/orgs/labtest/' + issuerID +'.md')

    const pubKey = keypair['issuerID'].keypair.public_key
    let check = await org.verifyCredential('issuerID', pubKey)
    // check is True

This is the process so far.

1. First we create an org object with the DID associated to it.
2. Then we create a new Keypait with Zenroom (or maybe we can reuse any key previously sotred in your wallet.)
3. We can now Sign the credential.
4. Verify

Set the member of this organizatio0n

    let org = new credentials.Organization("did:lor:lab:1000")
    org.name('Caelum Labs')

    let developer = new credentials.Persona('did:lor:lab:1001')
    developer.fullName('John','Smith', 'Matrix')

    org.member('developer', developer)
    
    // Now you can sign it and send it.

Create one action

    let action = new credentials.Action("did:lor:lab:1000", 20)
    
    let agent = new credentials.Persona('did:lor:lab:1001')
    action.agent(agent)

    
    // Now you can sign it and send it.
