I made a paper wallet on bitaddress with a BIP38 password. Recently, when I tried to import, I was given an error message stating that the passphrase was incorrect. I used the last (x) digits from the public address as the passphrase for the BIP38. My assumption is that maybe one character is capitalized when it shouldn't be.

Is there a script or software I can use to run through variations of the passphrase? It is 9 different characters, 8 letters, one number. Im looking for a program that would run abcde, abcdE, abcDE, abCDE, aBCDE, ABCDE, ABCDe, ABCde, ABcde, etc. using only these nine characters.

Any help would be appreciated, .05 bitcoin bounty to the solution.
