cipher - The Twenty Doors! (ROOM 1)

This is part of The Twenty Doors series.
The next one is The Twenty Doors! (ROOM 2)

---

You stand in a small, dark room. You have no idea where you are. Then, you see a message in front of you.

Welcome to the dungeon!

In each room, there is some paper, a hint, a door and a keypad. You must decipher the paper, using the hint, and enter what you think the answer is into the keypad. But don't answer wrong, or you will DIE!!!

Have fun, if you can...

ROOM 1:

You look at the paper:

uipefvyq

Then, you see that the hint is carved into the wall: Hello, over and over. The keypad has 9 numbers and an [ENTER] button.

Answer

Room 1:

The code is 14, if we decipher uipefvyq with the Vigenere cipher 'hello', we get neetruof, which is fourteen backwards.

I hope I won't DIE...
