W3C Data Integrity EdDSA Cryptosuites v1.0: Achieving Data Integrity using EdDSA with Edwards curves, W3C Recommendation, 15 May 2025 #470
Description
Formal name
W3C Data Integrity EdDSA Cryptosuites v1.0: Achieving Data Integrity using EdDSA with Edwards curves, W3C Recommendation, 15 May 2025
Overview
This specification defines a cryptographic suite for the purpose of creating, verifying proofs for Ed25519 EdDSA signatures in conformance with the Data Integrity VC-DATA-INTEGRITY specification. The approach is accepted by the U.S. National Institute of Standards in the latest FIPS-186-5 publication and meets U.S. Federal Information Processing requirements when using cryptography to secure digital information.
The suites described in this specification use the RDF Dataset Canonicalization Algorithm or the JSON Canonicalization Scheme - RFC 8785 to transform an input document into its canonical form. The canonical representation is then hashed and signed with a detached signature algorithm.
Work Plan
- The EC is following with W3C on this technical specification during the alignment meetings.
