hashcat as hash validator

[liget]

Yeah, it is here (I can possibly a special repo for it)
https://github.com/nesfit/fitcrack/tree/...hvalidator

Here is exact small and bit hacky patch how to do it:
https://github.com/nesfit/fitcrack/blob/...ator.patch

In fitcrack, we use it as a backed tool on a server to verify hashes (and we want to do so without opencl, etc), so user can see if entered hash is correct or not immediately.

So output of our "hashvalidator" has the format:
HASH OK
or
HASH Token length exception, etc..

I think this could be upstreamable as --verify-hashes-only. Do you think it could be useful for the community?
