Encrypt Binary Content to a JWE

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.EncryptBd, which encrypts binary content held in a BinData and writes the resulting JWE into a StringBuilder.

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

// Set the JWE protected header, specifying the key-management algorithm (alg) and the content-
// encryption algorithm (enc).
let header = chilkat::JsonObject::new();
let _ = header.update_string("alg", "A256KW");
let _ = header.update_string("enc", "A256GCM");
if jwe.set_protected_header(&header).is_err() {
    println!("{}", jwe.last_error_text());
    return;
}

// The 256-bit key-wrapping key (base64) for recipient index 0.  In production, obtain the key
// from a secure source rather than hard-coding it.
let base64_key = "YWJjZGVmZ2hpamtsbW5vcHFyc3R1dnd4eXowMTIzNDU=".to_string();
if jwe.set_wrapping_key(0, &base64_key, "base64").is_err() {
    println!("{}", jwe.last_error_text());
    return;
}

// Encrypt binary content held in a BinData, writing the resulting JWE into a StringBuilder.
let bd_content = chilkat::BinData::new();
let _ = bd_content.append_string("Binary content to encrypt.", "utf-8");

let sb_jwe = chilkat::StringBuilder::new();
if jwe.encrypt_bd(&bd_content, &sb_jwe).is_err() {
    println!("{}", jwe.last_error_text());
    return;
}

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