Helper routines to manage DIDs/VC/VPs

This module is a wrapper around the functions exported by SpruceID's DIDKit framework.

Verifiable Credential issuance

Verifiable Credential templates are stored as Jinja2 (TBD) templates in /vc_templates folder. Please examine each template to see what data must be passed to it in order to render.

The data passed to the template must at a minimum include:

  • issuer_did
  • subject_did
  • vc_id

For example, in order to render /schemas/member-credential.json:

from jinja2 import Environment, FileSystemLoader, select_autoescape
import idhub_ssikit

env = Environment(
    loader=FileSystemLoader("vc_templates"),
    autoescape=select_autoescape()
)
unsigned_vc_template = env.get_template("member-credential.json")

issuer_user = request.user
jwk_issuer = didkit.generate_ed25519_key()
jwk_subject = didkit.generate_ed25519_key()

did_issuer = didkit.key_to_did("key", jwk_issuer)
did_subject = didkit.key_to_did("key", jwk_subject)

data = {
    "vc_id": "http://pangea.org/credentials/3731",
    "issuer_did": did_issuer,
    "subject_did": "did:web:[...]",
    "issuance_date": "2020-08-19T21:41:50Z",
    "subject_is_member_of": "Pangea"
}
signed_credential = idhub_ssikit.render_and_sign_credential(
    unsigned_vc_template,
    issuer_did_controller_key,
    data
)
