How to create an AES encrypted self-extracting EXE.

        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {

  public static void main(String argv[])
  {
    CkZip zip = new CkZip();

    boolean success;

    //  Any string unlocks the component for the 1st 30-days.
    success = zip.UnlockComponent("Anything for 30-day trial");
    if (success != true) {
        System.out.println(zip.lastErrorText());
        return;
    }

    //  Initialize the zip object.  Because we're creating
    //  a self-extracting EXE in this example, the filename
    //  passed to NewZip will never actually be created.
    success = zip.NewZip("notUsed.zip");

    //  Indicate that AES encryption should be used:
    //  0 = No encryption
    //  4 = AES encryption
    zip.put_Encryption(4);

    //  Set the key length to 128-bits, 192-bits, or 256-bits
    zip.put_EncryptKeyLength(128);

    //  Set the password required to extract:
    zip.SetPassword("myPassword");

    //  Append a directory tree.  The AppendFiles does
    //  not read the file contents or append them to the zip
    //  object in memory.  It simply appends references
    //  to the files so that when WriteExe (or WriteZipAndClose,
    //  or WriteZip, etc.) is called, the files are compressed
    //  and added to the archive.
    boolean recurse;
    recurse = true;
    zip.AppendFiles("c:/temp/a/*",recurse);

    //  To create an EXE with a custom icon, set the ExeIconFile property:
    zip.put_ExeIconFile("apple.ico");

    //  Write "mySfx.exe"

    success = zip.WriteExe("mySfx.exe");
    if (success != true) {
        System.out.println(zip.lastErrorText());
        return;
    }

    System.out.println("EXE Created!");
