BUG: Unable to process attestation result when carrying Veraison's "key attestation" claims

[thomas-fossati]

Running:

let ear = Ear::from_jwt(    // Ear comes from rust-ear
    &attestation_result,
    jwt::Algorithm::ES256,  // jwt comes from jsonwebtoken
    &jwt::DecodingKey::from_ec_pem(
        verification_api
            .ear_verification_key_as_pem()
            .unwrap()
            .as_bytes()
    ).unwrap()
);

let ear = match ear {
    Err(e) => {
        println!("Unable to process attestation result ({})", e);
        return -1
    },
    Ok(r) => r,
};

Using:

• EAR JWT
• Verification key

Returns:

Unable to process attestation result (verify error: JSON error: expected `,` or `}` at line 1 column 1382)

The slightly confusing error from serde stems from the fact that "ear.veraison.key-attestation" is not handled in the submod parsing loop:

rust-ear/src/appraisal.rs
