How to download a file over HTTPS using Indy 10 and OpenSSL?

Question

I have the following task: download a file using HTTPS and authentication. Indy seems the way to go but for some reason it doesn\'t work so far. I have the following in plac

Answer 1

I finally abandoned Indy and OpenSSL and used WinInet for downloading. This is the code that worked for me:

function Download(URL, User, Pass, FileName: string): Boolean;
const
  BufferSize = 1024;
var
  hSession, hURL: HInternet;
  Buffer: array[1..BufferSize] of Byte;
  BufferLen: DWORD;
  F: File;
begin
   Result := False;
   hSession := InternetOpen('', INTERNET_OPEN_TYPE_PRECONFIG, nil, nil, 0) ;

   // Establish the secure connection
   InternetConnect (
     hSession,
     PChar(FullURL),
     INTERNET_DEFAULT_HTTPS_PORT,
     PChar(User),
     PChar(Pass),
     INTERNET_SERVICE_HTTP,
     0,
     0
   );

  try
    hURL := InternetOpenURL(hSession, PChar(URL), nil, 0, 0, 0) ;
    try
      AssignFile(f, FileName);
      Rewrite(f,1);
      try
        repeat
          InternetReadFile(hURL, @Buffer, SizeOf(Buffer), BufferLen) ;
          BlockWrite(f, Buffer, BufferLen)
        until BufferLen = 0;
      finally
        CloseFile(f) ;
        Result := True;
      end;
    finally
      InternetCloseHandle(hURL)
    end
  finally
    InternetCloseHandle(hSession)
  end;
end;
