you can download "John the Ripper" and
from terminal use bitcoin2john.py (followed by .dat location in litecoin) example for linux is: bitcoin2john.py ~/.litecoin/wallet.dat
to extract your password hash...then use the same program to guess your password with command: john (text document containing hash)
you can either download Kali Linux for a Virtual Machine, Live Cd/USB or installation and it comes with John the Ripper ( Kali Linux ) or you can download John the Ripper ( John The Ripper )...you will also need to make sure you have python installed on your system....kali comes with python
currently John the Ripper does not work on Windows
I am willing to crack passwords but I either need a copy of the extracted hash or the wallet.dat file
if you have an idea of what the password might be then you will find it faster...however brute force is always an option but takes quite a long time and should only be used when all else fails...
let me know if you need me to do it for you...just send me a personal message and I will send you my email address to send the hash or .dat file to
