1、字符:

var
  CRC:TIdHashCRC32;
begin
  CRC:=TIdHashCRC32.Create;
  Memo2.Text:=IntToStr(CRC.HashValue(Memo1.Text));
  CRC.Free;
end;

2、文件:

var
  MemSteam: TMemoryStream;
  CRC:TIdHashCRC32;
begin
  try
    CRC:=TIdHashCRC32.Create;
    MemSteam:=TMemoryStream.Create;
    if OpenDialog1.Execute then begin
      MemSteam.LoadFromFile(OpenDialog1.FileName);
      Memo2.Text:=IntToStr(CRC.HashValue(MemSteam));
    end;
  finally
    MemSteam.Free;
    CRC.Free;
  end;
end;
