I Need Decrypt Hard Drive Linux with Kali

I have a grub init

set gfxpayload=text

set default=0

set timeout=0

if keystatus --shift; then

set default=1

fi

menuentry 'Ubuntu 13.10 i686' {

set root='hd0,msdos1'

search --no-floppy --fs-uuid --set=root dd8b53b0-f1e4-4fe6-b9f6-7da0cd95f578

linux /vmlinuz-linux root=UUID=43a6fbe5-6dcd-4262-9f4c-0f6f3ecb2bf1 ro quiet cryptdevice=/dev/sda2:root root=/dev/mapper/root cryptkey=/dev/sda1:ext2:/key.bin loglevel=0

initrd /initramfs-linux.img

}

And I have the key.bin

How to open this crypted partition in other computer??
