For what do you need the password? For a file an internet account etc? Why do you need it cracked?
Please tell us these information, otherwise we dont know what kind of crack we should do.
Bruteforce is a good for cracking, especially for files (.zip .rar etc)
If you need like a facebook account etc cracked, it would be nearly impossible with software, because of the captchas.
A web developer gave me a script for 50$ in far format so I was able to see all the files in it then I paid him 50$ after that he gave me password 99988779 which is found to be incorrect after that he said I think I made a mistake sorry get a password unlocked to unlock the password that's it
