Start by entering simple strings and see what the result is. Then gradually increase the length of the string to try and get a feel for what the algorithm is doing. It's kind of a brute force method but not a blind one. Your mileage may vary. I'm assuming you can do these steps. After you get used to seeing normal strings in their hashed formats, it should begin to come natural for you to reverse the steps starting with a hash.
If this is good advice, then I'm glad I could contribute. Otherwise, see what someone more skilled in this area can suggest.

Or well, yeah, this; if you have access to deciding and encrypting your own plaintexts. Based on the initial post though, I assume that isn't the case.
