Delphi ActiveX

Example: Crypt2.SetEncodedIV method

Demonstrates how to call the SetEncodedIV method. 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;

...

procedure TForm1.Button1Click(Sender: TObject);
var
crypt: TChilkatCrypt2;

begin
crypt := TChilkatCrypt2.Create(Self);

crypt.CryptAlgorithm := 'aes';
crypt.CipherMode := 'cbc';
crypt.KeyLength := 256;

// Note: The lenght of the IV is equal to the block size of the symmetric encryption algorithm.
// The block size for AES is 16 bytes.  Therefore, the IV is 16 bytes regardless of the encryption strenght (128-bit, 256-bit, etc.)
crypt.SetEncodedIV('000102030405060708090A0B0C0D0E0F','hex');
