How to encrypt post parameters in Inno Setup

Question

I have to post some user entered dynamic data to my server while installing. I can post the data successfully. But to post the data securely i have to encrypt the data while posting. I don't know how to do this..

Here is my code,

procedure CurStepChanged(CurStep: TSetupStep);
var
  WinHttpReq: Variant;
begin
  if CurStep = ssInstall then
  begin
    if AutoCheckRadioButton.Checked = True then
    begin
      WinHttpReq := CreateOleObject('WinHttp.WinHttpRequest.5.1');
      WinHttpReq.Open('POST', '<web_server>', false);
      WinHttpReq.SetRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
      WinHttpReq.Send('<need to encrypt data>');
      { WinHttpReq.ResponseText will hold the server response }
    end;
  end;
end;

Thanks in advance for your help

If your web server supports HTTPS and the URL is using https protocol, the OLE object should handle it for you automatically. This ensures the data is encrypted en-route from the client to your server. — KC Wong, Jan 03 '17 at 07:15

Just use an HTTPS URL, like:

https://www.example.com/

The encryption happens automatically.
