Cracking Veracrypt hidden volume - outer volume pw known

[b8vr]

After this command:

Code:

.\hashcat.exe -m 29431 -a 0 hash.txt passwords.txt -o pwcracked.txt -w 4 -O -S -n 1 --force

I was receiving a "No hashes loaded." error, I had to convert the *.txt file to UTF-8 format and now everything seams to be working fine. Hashcat is working now

Yes, your use of verscrypt2hashcat is correct if it's an encrypted container and not a bootable partition.

Your hashcat command also looks good, although I don't understand why you use -n 1.... 
That is used for fine tuning which hashcat does automagically and setting to 1 would give a negative impact on hashcat performance.
