Get a JWS Unprotected Header

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.GetUnprotectedH, which copies the optional unprotected header of a signature into a JsonObject.

let jws = chilkat::Jws::new();

// Load the JWS compact serialization.
let jws_compact = "eyJhbGciOiJIUzI1NiJ9.VGhpcyBpcyB0aGUgY29udGVudCB0byBzaWduLg.<signature>".to_string();
if jws.load_jws(&jws_compact).is_err() {
    println!("{}", jws.last_error_text());
    return;
}

// Copy the optional unprotected header of signature 0 into a JsonObject.  This applies to JWS in a
// JSON serialization form that carries an unprotected header.
let json = chilkat::JsonObject::new();
if jws.get_unprotected_h(0, &json).is_err() {
    println!("{}", jws.last_error_text());
    return;
}

json.set_emit_compact(false);
println!("{}", json.emit().unwrap_or_default());
