    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var zip = new chilkat.Zip();

    // To verify a password for a Zip, the Zip must be opened:
    var success = zip.OpenZip("myProtected.zip");
    if (success !== true) {
        console.log(zip.LastErrorText);
        return;
    }

    // Set the password to be verified:
    zip.DecryptPassword = "secret";

    var passwordOk;
    passwordOk = zip.VerifyPassword();
    if (passwordOk == true) {
        console.log("Password is correct.");
