var success = false;

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

var crypt = new CkCrypt2();
var zip = new CkZip();

success = zip.NewZip("test.zip");
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

//  Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip
var bd = new CkBinData();
bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex");
zip.AddBd("binaryData.dat",bd);

//  Add the string "Hello World!" to the .zip
zip.AddString("helloWorld.txt","Hello World!","utf-8");

zipFileInMemory = zip.WriteToMemory();

//  We could save these files to a file, and it is a valid .zip
var fac = new CkFileAccess();
success = fac.WriteEntireFile("test.zip",zipFileInMemory);
if (success == false) {
    console.log(fac.LastErrorText);
    return;
}

console.log("Zip Created!");
