[Implementation] CRYSTALS-Dilithium5 in W3C Verifiable Credentials

Hello CCG,

I wanted to share a successful implementation of a Post-Quantum
Cryptography (PQC) stack within the W3C VC/DID framework.

Attached are screenshots demonstrating a full lifecycle using
*CRYSTALS-Dilithium5* (Dilithium5VerificationKey2023):

   1.

   *holder_did.json*: A DID Document utilizing a Dilithium5 public key.
   2.

   *verifiable_credential.json*: A university degree credential issued and
   signed with Dilithium5.
   3.

   *verifiable_presentation.json*: A complete presentation where the
   holder-binding is also secured via Dilithium.

Given the NIST standardization of Dilithium, I believe this demonstrates
the readiness of PQC suites for production-grade Decentralized Identity.

Looking forward to any feedback or discussion on further standardizing
these PQC-based verification methods.

Best,

Amir Hameed Mir
