    Thread: Hashcat very slow between benchmarks
Post: RE: Hashcat very slow between benchmarks

Theoretically, could you generate those kernels on an otherwise identical setup, and then copy them to the kernel cache area? Also, if it's the kernel generation, I would expect the delay before any ...

Post: RE: Hashcat very slow between benchmarks

Any view into where resources are going during the delay? Can you strace it to see what hashcat is doing in that moment?

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...

You can supply a custom charset using --custom-charset[1-4] files. The ./charsets/ directory has some stock ones, including the ./charsets/standard/German/ directory. You can combine up to four multip...

Post: RE: Best bang for buck card(s)?

The numbers that I posted, plus the Google doc, should let you compare R9 290X with 970 SC. I prefer NVIDIA over AMD, even with a slightly lower speed, but YMMV. :)

You can generate a list of masks following these restrictions, and then pass a file containing those masks to hashcat. https://thesprawl.org/projects/pack/#specifying-maximum-complexity

Looking through the dictionaries won't tell you which rule was used. For future work, or if you want to run your job again, check out --debug-mode. Mode 4 may be what you're looking for. This won't...

Specifically, the feature request would be something along the lines of "ignore 00-suffixed plains as duplicates even when using --keep-guessing".

I guess I'd also need to combine that with a hex mask that leaves out 00 for the last char(s).

That's not quite how specifying a mask works. IF you don't know which characters are in which positions, you want something more like this -- first definiting a custom character set, and then using it...

There is no way to combine hashes that I know of. It would be a very interesting and useful feature, but it might be difficult to implement.

Almost not at all. I guess it would alter the behavior for any hashes that already keep guessing (is it 7-Zip?)

If it's WinZip-compatible ZIP, then it would be covered by mode 13600. You'll have to extract the hash using zip2john (from John the Ripper). This thread may be useful: https://hashcat.net/forum/th...
