Geth Ethereum Keystore password recovery

[LowellChief]

Thank you Bogeyman. That worked and I got HC running. I tried to run the dive.rule with my txt file but it was going to take until April to finish running. Next, I tried the best64.rule and it took about 2 hours to run but did not find the PW after trying about 8400 possibilities. I know my password is most likely between 8 and 20 characters and may be a combination of words/numbers/symbols in my text file.

Any suggestions of what rule might work the best and be most efficient?
