Create Password Protected Zip containing a Single File.

See more Zip Examples

Create a password-protected .zip containing a single file. (This uses the older Zip 2.0 encryption scheme, which is weaker and not as secure as AES encryption, which Chilkat Zip also supports.) Delphi ActiveX

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Chilkat_TLB;

// See Global Unlock Sample for sample code.
