Subject: a question about encrypted 7z hashes
Currently the 7z2john.py does not support 7z archives with unencrypted file
names. However, hashcat has a utility that will do this. I was wondering
about the compatibility between the two hashes.
Could you use a hash generated by the hashcat extractor utility with John
the Ripper? There seem to be some differences between the two hashes.
Here is an example from a test archive:
Output from 7z2john.py:
$7z$0$19$0$1122$8$4a44f9c4689caf900000000000000000$3341692866$208$201$d8153b86f6a78ce75e042338531d9aee5368a7a26f34f24ac8dbb0677815399917c16aeb7546e4dc0

Output from 7z2hashcat.pl:

I guess I don't understand hashes. Shouldn't they be the same as the
password is the same? Why are they different? Could I use the output from
the 7z2hashcat.pl hash as input to JTR as I can't get the hash with any
available JTR tools?
I've tried everything I can think of using hashcat and just wanted to see
what I can do using JTR. Also I can run JTR on my cpu while running
hashcat on my gpu.
Thanks for any help.
