Five First Public Working Drafts published by the Verifiable Credentials Working Group

The Verifiable Credentials Working Group has published five First Public Working Drafts today. These drafts fall into two groups.

1. The first group consists of new minor versions of published Recommendations that are maintained by the Working Group, without any significant change. These are:
   • Verifiable Credential Data Integrity 1.1: This specification describes mechanisms for ensuring the authenticity and integrity of verifiable credentials and similar types of constrained digital documents using cryptography, especially through the use of digital signatures and related mathematical proofs.
   • Data Integrity EdDSA Cryptosuites v1.1: This specification describes Data Integrity cryptographic suites for use when creating or verifying a digital signature using the Ed25519 instantiation of the Edwards-Curve Digital Signature Algorithm (EdDSA).
   • Data Integrity ECDSA Cryptosuites v1.1: This specification describes Data Integrity cryptosuites for use when generating a digital signature using the Elliptic Curve Digital Signature Algorithm (ECDSA).
2. The second group consists of new specifications, listed as new deliverables in the new Working Group Charter. These are:
   • VCALM v1.0: This specification provides data model and HTTP protocols to issue, verify, present, and manage Verifiable credentials used in a credential ecosystem.
   • Verifiable Credential Barcodes v1.0: This specification describes a mechanism to protect optical barcodes, such as those found on driver's licenses (PDF417) and travel documents (MRZ), using Verifiable Credentials. The Verifiable Credential representations are compact enough such that they fit in under 150 bytes and can thus be integrated with traditional two-dimensional barcodes that are printed on physical cards using standard printing processes.

The Working Group welcomes comments via the GitHub repository issues, whose reference is in the header of the respective documents.
