I password protected it a couple of years ago and would really like access. I don't think I encrypted file names, so when I run the "7z2john.py" script, I get this message: file.7z : 7-Zip files without header encryption are *not* supported yet! >From googling, I see threads where an author mentions adding it in the future, but on github the file hasn't been updated in over two years. I've tried searching for a later version but I can't find it. I've used "7z2hashcat.pl" to get the hash, but when trying that hash file in john it doesn't seem to want to load. Maybe I am doing something wrong in the commands? C:\johnomp\run>john --format=7z outfile.hashes No password hashes loaded (see FAQ) Is there any alternative way to get the hash into a format that I can use with john? I have very little knowledge of what the password is so I am trying to do multiple avenues of cracking to maximize processing power and get it sooner. Thi would be a good help. If now, can someone recommend a good cpu based software for ubuntu 12.04 I can run? Thank you.
