Needing some help here. I've just discovered I have some eth in an old address I created when initially playing around with eth mining late last year. I have the key file from the keystore directory (the one beginning UTC) but I can't remember all of the password - it was a six-letter word followed by four numbers. I can remember the word, but not the numbers.
So that's 9999 possibilities, which is obviously not feasible to try out by hand. Is there any tool available to automate this?
