Subject: Re: Cracking Word files?
Ah okay. Thanks for the tip.
So what I did what feeding john with the hash. The first file (which I
also provided to you in this email thread) was cracked after about 7
minutes in my virtual machine. Then I created a new file with the
password "password23". Now, currently john is already trying to crack
this file for now about 2 hours and it is still not finished yet.
I heard that john can be run on gpus. Is there some sort of manual
that explains how to do this? I've got a NVIDIA GeForce 9400M in my
Macbook. So, I'm wondering if this is technically (dispite of
performance issues) possible. I mean, I just want to try it .
