Laravel, Как записать бинарную строку в базу?

$this->user->create([
                'id' => $newId,
                'name' => $data['name'],
                'email' => $data['email'],
                'passwd' => 'not_activated',
                'passwd2' => md5($data['name'] . $data['passwd'], true),
                'Prompt' => $data['Prompt'],
                'answer' => $data['answer'],
                'idnumber' => request()->ip(),
                'creatime' => Carbon::now()
            ]);
