This document explains how to create and verify a Selected-Disclosure JWT (SD-JWT) using the EUDI Wallet IT Python library. It also covers how to validate proof of possession enabling three key operations: +1. **Issuer**: Generate an SD-JWT with selective disclosure capabilities. +2. **Holder**: Select claims to disclose and create a presentation. +3. **Verifier**: Validate the SD-JWT and verify the disclosed claims. + +### Requirements +- Python version as configured in the CI of this project. +- Install the library via `pip`: +```bash +pip install pyeudiw +``` + +- **Key Requirements**: + - All keys must be in JWK (JSON Web Key) format, conforming to [RFC 7517](https://datatracker.ietf.org/doc/html/rfc7517). + - You can use a library like `cryptojwt` to generate or manage JWKs. Example: + +```bash +from cryptojwt.jwk.ec import new_ec_key + +# Generate an EC key pair +issuer_private_key = new_ec_key('P-256') + +# Serialize the keys +issuer_keys = [issuer_private_key.serialize(private=True)] # List of private keys +public_key = issuer_private_key.serialize() # Public key +``` +--- + +## 1.
