Subject: use data from known password zipfile created by the same machine/user?


I have two zip files I created on the same machine. One password I know,
the other I have lost. I have created zip2john hash files for both zip
files. I know the password for. I don't.

Is it possible to gather any kind of hash result or salt from processing
the file that will aid jtr in figuring out easier? password is very similar to: 1Jump.H1gh3r
It's highly likely I used similar kinds of letter replacement for

I tried:
./john File2.hash
./john --wordlist=rockyou.txt --rules:All File2.hash

If it lends any clues to a good method or approach to take the File2.hash
starts like this:$pkzip2$3*2*1*0*8*24*40ce*92f4*

I feel like I am not approaching this in a smart method.

Any help is appreciated.
