Sorry it was actually dm-crypt with LUKS. I just checked and had no idea before.
I have generated the possible permutation list. Wouldn't it make sense to just brute force LUKS with the 100,000 possible combinations or is that a bad idea?
Sorry, I am trying to understand if it is possible to do this or I should just give up hope.
