function chilkatExample() {

    var success = false;

    // Note: This example requires Chilkat v9.5.0.85 or greater.

    // We have the following x and y values in hex (for an EC point on the P-256 curve).
    var x = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83";
    var y = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9";

    var pubkey = new chilkat.PublicKey();
    success = pubkey.LoadEcdsa("secp256r1",x,y);
    if (success == false) {
        console.log(pubkey.LastErrorText);
        return;
    }

    console.log("Success.");
