    Thread: Brute Force- Mask,ntml hash?
Post: RE: Brute Force- Mask,ntml hash?

There is no way to determine the length of a plaintext from the hash. This is true for all hashes, and is by design. You cannot know the length until you have cracked it. You can use other informat...

Post: RE: Is This Possible?

What is the use case for wanting this behavior? If it's for a reason like this (https://hashcat.net/forum/thread-6293.html), it's not a good one. :) Within hashcat itself, you have four options for ...

You can use the --hex-charset option to specify this set of binary. Edit: specifically, something like: --hex-charset -1 000102030405060708 ?1?1?1?1?1?1?1?1 ... or however long your expected string...

    Thread: Default Graphics card

There is often a setting in the BIOS to select which GPU to use as the primary. It shouldn't have an effect on hashcat - it should happily use them both as long as they're both supported and the dr...

Yes, in incremental mode, a length will be exhausted before the next length is started. Also, the Candidate progress display shows a range. It is normal for this to only change when another range i...

There's no way to do this with hashcat - it's not a rules-level problem, but an algorithm-level problem. Outside of hashcat, this algorithm isn't natively supported by MDXfind and probably not by H...
