I found where she states all that is needed to solve it are in HER BOOK. Leading me to think it is not Fenn's poem and therefore the key I would not be able to help solve. You can't brute force it even with the number of characters because of the spaces taken out. So no calculator can help crack it, even if you have the character count. I ran up to 100 characters for an 'unknown key' and it can't crack it because of lack of spacing in both the cipher and the theoretical key, because you just have a character count that she will give. If she gives the character count, you can taker her book and most likely find the key. But you can't take the character count and the cipher with no spacing and find the key.
