Get the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.GetProtectedHeader, which copies the decoded shared JWE protected header into a JsonObject.

let jwe = chilkat::Jwe::new();

// Load the JWE.
let jwe_compact = "eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMjU2R0NNIn0.<...>.<iv>.<ciphertext>.<tag>".to_string();
if jwe.load_jwe(&jwe_compact).is_err() {
    println!("{}", jwe.last_error_text());
    return;
}

// Copy the decoded shared JWE protected header into a JsonObject.  Only the protected header is
// returned; it is not merged with the unprotected or per-recipient headers.
let json = chilkat::JsonObject::new();
if jwe.get_protected_header(&json).is_err() {
    println!("{}", jwe.last_error_text());
    return;
}

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