Excuse my dumb question, but.. did you even read this thread?

Short summary:

• JackTheRipper = CPU cracking
• Hashcat = GPU cracking
• GPU waaaay faster than CPU

But, to be honestly.. if you need to ask such questions on this forum.. i don't think you are capable of "cracking a wallet".
May i ask whether you have forgotten your password (which makes it easier to crack your wallet file if you remember parts of your password)?
Or are you trying to "make money" with cracking wallets? In this case, you can pretty much forget that and should turn over to something which isn't pure waste of time.


And for the future: Please google first. This forum (especially this subforum) is related to Bitcoin. Its not a guide on how to crack wallets. Particularly not if you are trying to do blackhat-stuff.
