Crate baseid_anoncreds 

baseid-anoncreds

Hyperledger AnonCreds support for BaseID.

Provides AnonCreds credential schema definition, credential issuance/holding, proof request matching, and proof response construction. Enables interoperability with the Canadian Aries ecosystem (BC Wallet, ACA-Py).

Features

• Schema & CredentialDefinition: Define credential types with validation.
• AnonCredsCredential: Parse ACA-Py JSON, map to W3C VC for unified display.
• ProofRequest / ProofResponse: Match credentials to proof requests and build responses.
• CredentialHolder: Store credentials and respond to proof requests.

Design Decision

AnonCreds uses CL (Camenisch-Lysyanskaya) signatures which are mathematically complex. This crate provides the data model and holder logic; actual CL proof generation would wrap the Hyperledger anoncreds-rs library.
