The passwords are 'one way' encrypted. An attacker could set their computer going to try every different combination of password until they discover one that matches the hash solution. When they have, they know the password. It just takes a lot of patience and fast computation. You cannot determine a password from the hash directly, only in the way that I hope I've explained.Don't know if one of the columns is a "hashed" version of the password that can be translated into the real password? Well above my understanding! I've changed mine. But as your e-mail address is there it may mean increased spam?
Fortunately, the e-mail address I used on that site is a dedicated masked e-mail so I should be able to identify if spam is resulting from that hack. Haven't seen any though as yet.
