Are you sure? I've tried john --format=netntlmv2 /root/Desktop/hash with the following and get "No password hashes loaded (see FAQ)".

Yeah I'm sure, it's still in my console buffer:
Code:
$ ../run/john test
ntlmv2-opencl: One or more hashes rejected due to salt length limitation.
Max supported sum of Username + Domainname lengths is 27 characters.
Try the CPU format for those.
Loaded 1 password hash (netntlmv2, NTLMv2 C/R [MD4 HMAC-MD5 32/64])
Press 'q' or Ctrl-C to abort, almost any other key for status

Use the "--show" option to display all of the cracked passwords reliably

As you can see the GPU format rejects it but tells you why, and then the CPU format loads and cracks it. The latter just use OpenSSL so has no length limits but is likely a lot slower than HashCat.

I did remove the binary crap that epixoip mentioned. I tried pasting the correct one here but the forum re-adds the binary crap at the line wrap.

Could you explain what needs to be removed from the hash? I would really appreciate it.
