Hash of veracrypt file
#1
Hey all,

I've spent quite a few hours this evening trying to do this myself, but I think I'm in over my head.

Long story short, I have a veracrypt (.hc) file from years ago that I'd like to get in to, and I remember enough of the password to generate a list of <350 passwords (a few o or 0, e or 3 permutations in a 30+ character password). I thought I'd extracted the first 512 bytes correctly using dd for windows, and tried again with a hex editor to extract the 01 0A 2F format and the symbol format, and I've run the password list against all three hash files using various 137XY combos hoping I got one of them right. However, every attempt comes back exhausted.

Code:
Session..........: hashcat
Status...........: Exhausted
Hash.Type........: VeraCrypt PBKDF2-HMAC-SHA512 + XTS 1536 bit
Hash.Target......: hc3.hash
Time.Started.....: Thu Apr 05 22:34:08 2018 (1 min, 3 secs)

Started: Thu Apr 05 22:32:41 2018
Stopped: Thu Apr 05 22:35:12 2018

Is there a sure-file way to extract the hash that I couldn't possibly screw up?

This is my starting code
Code:
hashcat64.exe -m 13723 hc3.hash test.dict
with different last two digits. If I got the hash correctly, then I can figure out areas where I may mis-remember my old password more than I thought and would likely be able to double or quadruple the list file.

Any help would be appreciated.
