Quick Start Instructions

  1. Download and unzip to any directory. Unzipping will create a chilkat-9.5.0-delphi subdirectory containing the following files:
    README.txt              A text file pointing to this document and other sources of information.
    ChilkatDelphiXE.dll     The Chilkat 32-bit DLL providing the implementation for all Chilkat objects.
                            This DLL is not an ActiveX.  It does not need to be registered via regsvr32.
    ChilkatDelphiXE64.dll   The Chilkat 64-bit DLL providing the implementation for all Chilkat objects.
    LICENSE.txt             The full EULA license agreement.
    *.pas                   A Pascal interface source file for each Chilkat object.
  2. Start the Delphi RAD Studio IDE and create a new VCL Forms Application. Save it to the chilkat-9.5.0-delphi directory where the ChilkatDelphiXE.dll and Chilkat *.pas files are located.
  3. Add a TButton and TMemo to the form.
  4. Add each of the Chilkat interfaces that will be used to the "uses" section. For example, if the project will use only Crypt2.pas, add "Crypt2" to the "uses" section:
      Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
      Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Crypt2;
  5. Select Project --> Add to Project and then add each of the Chilkat .pas sources listed in the "uses" section to your project. In this case, add "Crypt2.pas" to the project.
  6. Double-click on the Button1 on your form to add code to handle the click event. For example, to AES encrypt some text, add the following code, which can be found at Delphi AES Encryption
    procedure TForm1.Button1Click(Sender: TObject);
    crypt: HCkCrypt2;
    success: Boolean;
    ivHex: PWideChar;
    keyHex: PWideChar;
    encStr: PWideChar;
    decStr: PWideChar;
    crypt := CkCrypt2_Create();
    success := CkCrypt2_UnlockComponent(crypt,'Anything for 30-day trial');
    if (success <> True) then
    ivHex := '000102030405060708090A0B0C0D0E0F';
    keyHex := '000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F';
    encStr := CkCrypt2__encryptStringENC(crypt,'The quick brown fox jumps over the lazy dog.');
    decStr := CkCrypt2__decryptStringENC(crypt,encStr);
  7. Build the project to create the output .EXE
  8. Important: Copy the ChilkatDelphiXE.dll to the same directory where the output .EXE is located. This will typically be in a subdirectory such as "Win32/Debug". The ChilkatDelphiXE.dll must be located in the same directory as your application's .EXE.
  9. Run.
  10. Note: The ChilkatDelphiXE.dll is a 32-bit Windows DLL. It can only be loaded from a project that is built for the Win32 Target Platform.
  11. Important: For 64-bit builds, rename ChilkatDelphiXE.dll to ChilkatDelphiXE32.dll. Then rename ChilkatDelphiXE64.dll to ChilkatDelphiXE.dll. The pathname of the DLL must match the pathname specified in each of the Chilkat .pas source files.
