Exactly. From what I know there's no way to get the right value from a given MD5-sum, only using that sum. You have to make some permutations using different characters, numbers, etc. and then encrypt it using MD5, and then compare with the MD5-sum you wanted to "crack".

My favorite tool for cracking MD5 is "Cain", and it uses exactly that method.
