function chilkatExample() {

    var success = false;

    // Note: This example requires Chilkat v9.5.0.66 or later.

    // Load a PEM file into memory.
    var sbPem = new chilkat.StringBuilder();
    success = sbPem.LoadFile("qa_data/pem/rsa_passwd.pem","utf-8");
    if (success !== true) {
        console.log("Failed to load PEM file.");
        return;
    }

    // Load the PEM into a private key object.
    var privKey = new chilkat.PrivateKey();
    success = privKey.LoadEncryptedPem(sbPem.GetAsString(),"passwd");
    if (success !== true) {
        console.log(privKey.LastErrorText);
        return;
    }

    // Get the private key in JWK format:
    var jwk = privKey.GetJwk();

    // The GetJwk method will return the JWK in the most compact JSON format possible,
    // as a single line with no extra whitespace.  To get a more human-readable JWK (for this example),
    // load into a Chilkat JSON object and emit non-compact:

    var json = new chilkat.JsonObject();
    json.Load(jwk);
    json.EmitCompact = false;
    console.log("RSA Private Key in JWK format:");
    console.log(json.Emit());
