Create a JWS into a StringBuilder

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.CreateJwsSb, which creates a JWS and writes it into a StringBuilder.

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

// Set the protected header for signer 0, specifying the signature algorithm (alg).
let header = chilkat::JsonObject::new();
let _ = header.update_string("alg", "HS256");
if jws.set_protected_header(0, &header).is_err() {
    println!("{}", jws.last_error_text());
    return;
}

// Set the payload to be signed.
let b_include_bom = false;
if jws.set_payload("This is the content to sign.", "utf-8", b_include_bom).is_err() {
    println!("{}", jws.last_error_text());
    return;
}

// Provide the HMAC key (base64) for signer 0.  In production, obtain the key from a secure source
// rather than hard-coding it.
let base64_key = "YWJjZGVmZ2hpamtsbW5vcHFyc3R1dnd4eXowMTIzNDU=".to_string();
if jws.set_mac_key(0, &base64_key, "base64").is_err() {
    println!("{}", jws.last_error_text());
    return;
}

// Create the JWS and write it into a StringBuilder.
let sb_jws = chilkat::StringBuilder::new();
if jws.create_jws_sb(&sb_jws).is_err() {
    println!("{}", jws.last_error_text());
    return;
}

println!("{}", sb_jws.get_as_string().unwrap_or_default());
