I lost 20 BTC my HD died and I lost wallet backup. I just want keep my pc running a couple of days trying to get the key, I know it is a waste of time but id like to know if any software can do it.
The simple solution would be to try and recover the hard disk,brute forcing to get the private key, good luck with that. There is no specific tool to bruteforce but look at github you might find some useful programs that might suite you.
