thanks keychainX! It seems powerful. I'm just learning how to use it while the computer is doing some mask attacks. I'll probably combine both approaches.

A couple of questions regarding MultiBit Classic wallet: I see many people complaining about corrupted MultiBit wallets not opening with the correct password. I *believe* my wallet files are ok because they load into MultiBit Classic for Mac or, when I extract keys o see transactions with other scripts, they do not complain, but:

... is there a way to be sure the wallet files have not been corrupted?
... is there the possibility that hascat (or other recovery scripts) is not able to open the wallet even if they find the correct password?

Thank you!
