# </html>dari pola ini kita bisa lihat bahwa pintu-pintu tersebut menggunakan md5 hash dari angka 1 sampai 13 sebagai nama pintunya.
jadi kita bisa coba buka pintu yang tidak ada di halaman tersebut yaitu pintu dengan nama md5 dari angka 14 misalnya yaitu "aab3238922bcc25a6f606eb525ffdc56"
echo -n 14 | md5sum
aab3238922bcc25a6f606eb525ffdc56

kita coba buka pintu dengan md5 0 yaitu "cfcd208495d565ef66e7dff9f98764da"
echo -n 0 | md5sum
# cfcd208495d565ef66e7dff9f98764da
