unusually short crc from 7z2hashcat
#1
Hi all,

I'm trying to recover some old files that I put into password protected .7z files back in 8th grade (nothing interesting in them, just really for fun.) One file generates a really long hash that hashcat will take and process:

hash modified by philsmd (see forum rules):
$7z$1$19$0$$8$iv$crc$len1$len2$data$len3$coder attributes

but the second file only has a short hash:
hash modified by philsmd (see forum rules):
$7z$128$19$0$$16$iv$crc$len1$len2$data

But when I enter that into hashcat it gives me the following error:
Code:
Hashfile 'F:\*****\hashes5.txt' on line 1 ($): Signature unmatched

Hashfile 'F:\*****\hashes5.txt' on line 2 (): Line-length exception

I tried making a 7z file with a known password, and I also got a similar short hash that wouldn't work. Any suggestion on what I might be doing wrong? I really did look for an answer before coming here, but I wasn't able to find anything.
