This method seems to be duplicated in your project.

    {
        $tableSize = 256;

        $table = [];

        for ($iterator = 0; $iterator < $tableSize; ++$iterator) {
            $temp = 0;
            $a = $iterator;
            for ($j = 0; $j < 8; ++$j) {
                if ((($temp ^ $a) & 0x80) !== 0) {
                    $temp = (($temp << 1) ^ $polynomial);
                } else {
                    $temp <<= 1;
                }
                $a <<= 1;
            }
            $table[$iterator] = $temp & 0xff;
