Are you sure $total of type Illuminate\Database\Eloquent\Builder|integer|mixed can be used in concatenation?

            $bar = $this->output->createProgressBar($total);

It seems like $total can also be of type Illuminate\Database\Eloquent\Builder; however, parameter $max of Symfony\Component\Console\Style\SymfonyStyle::createProgressBar() does only seem to accept integer, maybe add an additional type check?

            $bar->setFormat('%current%/%max% [%bar%] %percent:3s%% %elapsed:6s%/%estimated:-6s% %memory:6s%');

            $records =  $this->model->orderBy('id', 'asc')->where('encrypted', 0)->get();
            foreach ($records as $record) {

                $bar->advance();

The assignment to $record is dead and can be removed.
