Module data_integrity 

Data Integrity proof creation and verification.

Implements the eddsa-rdfc-2022 cryptosuite for signing and verifying W3C Verifiable Credentials with Data Integrity proofs.

Canonicalization

This implementation uses RDFC-1.0 (RDF Dataset Canonicalization) via the baseid-jsonld crate. The document and proof options are expanded from JSON-LD into N-Quads and then canonicalized per the W3C RDFC-1.0 specification, producing deterministic output for hashing and signing.
