This is the reference implementation of the IETF SD-JWT specification written in Rust. Supported version: 7.

Note: while the project is started as a reference implementation, it is intended to be evolved to a production-ready, high-performance implementations in the long-run.

Note: the current version of the crate is 0.0.x, so the API should be considered as experimental. Proposals about API improvements are highly appreciated.

fn demo() {
    let mut issuer = SDJWTIssuer::new(issuer_key, None);
    let sd_jwt = issuer.issue_sd_jwt(claims, ClaimsForSelectiveDisclosureStrategy::AllLevels, holder_key, add_decoy, SDJWTSerializationFormat::Compact).unwrap();

    let mut holder = SDJWTHolder::new(sd_jwt, SDJWTSerializationFormat::Compact).unwrap();
    let presentation = holder.create_presentation(claims_to_disclosure, None, None, None, None).unwrap();

    let verified_claims = SDJWTVerifier::new(presentation, cb_to_resolve_issuer_key, None, None, SDJWTSerializationFormat::Compact).unwrap()
                            .verified_claims;
}
