You probably want to create LUKS over LV (LUKS over LVM) and after normal LVM resize just issue cryptsetup resize.

BTW, thanks for the last message, I got things to work because of your help, here's how I did it: -cd /dev/mapper - e2fsck -f luks-vg1-lvfiles - resize2fs luks-vg1-lvfiles - cryptsetup luksClose luks-vg1-lvfiles - lvreduce -L -4G /dev/vg1/LVfiles - cryptsetup lukeOpen /dev/vg1/LVfiles luks-vg1-lvfiles - resize2fs luks-vg1-lvfiles to resize the root LV, I just used the rescue CD but had to copy the LVM commands on a USB drive since they dont seem to be included for some strange reason.
