password length for -a attack against truecrypt

[Snoopy]

https://hashcat.net/wiki/doku.php?id=fre...pt_volumes
quote:
if TrueCrypt uses a hidden partition or volume, you need to skip the first 64K bytes (65536) and extract the next 512 bytes

so if you look close -> No hashes loaded

inside your file.hash no valid hash was found, so hashcat is unable to start the attack
