DID User Agent Extension

This an EARLY ALPHA of an extension that augments a Web browser with low-level DID functionality, DOM API prollyfills, and a generic wallet-like DID User Agent UI that allows for management of DIDs, credentials, and datastore interactions.

The following features being developed (subject to change):

• HTTP Header to provide awareness of DID features to servers.
• navigator.did.supportedMethods for dynamic awareness of supported DID Methods.
• navigator.did.resolve() - resolve the DID Documents of supported DID implementations.
• navigator.did.requestAccess():
  • Request disclosure of a DID + signed challenge for authentication.
  • Request a grant of datastore permissions (capabilities model is pending).
• navigator.did.requestCredentials() - request presentation of Verifiable Credentials via Presentation Exchange evaluation and fulfillment.
• navigator.did.issueCredentials() - initiate a credential issuance flow via Credential Manifest request and fulfillment. (effectively a proxy of Hub-based credential issuance Actions).
• Identity Hub interactions for Permissions, Actions, Collections, and Profile interfaces.
