Change encrypted disk passphrase

Hi Guys!

So I installed 12.10.. and during the install I choose to encrypt the SSD.

However my house mate likes to borrow my computer every now and again. And the password I choose is one he has trouble remembering..

Is it possible to change it? So I could make it more memorable...

Thanks..

Code:

---

cryptsetup luksChangeKey /dev/sdx

---

where sdx is your encrypted partition.

Awesome!

Thanks
