Not a lot of options here. The major wrappers and GUIs are tracking the modern/current hashcat. What's driving your need for this older hashcat version?

There are currently no other options, for the reasons stated in this thread and by atom in the thread that you referenced.

I honestly haven't tried this before, but instead of trying to load it all into a mask, you might also be able to just do a hybrid attack (mask + wordlist), where the wordlist is just one line with yo...

If it's only happening for certain hash types, it's probably not a driver problem. How many rules are you using? This sounds like there are more end-result rules than will fit in GPU memory.

Post: RE: On-the-fly loading of gz wordlists

I'm not sure, but I think that decompressed data can be used "on the fly" - as soon as it's decompressed, without having to wait for the entire file to decompress.

Yes, that seems right. It would have to decompress the whole thing first, enough to analyze the statistics and then cache them. so I assume there would be some duplicated work, just like dictionary ca...

There's no online calculator that I'm aware of. Just do the math: 1. Calculate how many possibilities your mask will generate. For example, ?a has 95 possibilities, so ?a?a?a?a is 95^4 or 81450...

FWIW, for some attacks I've seen it's good to have one core per GPU. I haven't seen anything that would benefit from multiple cores per GPU.

And in your case, if it's 8 lower case, the mask would be ?l?l?l?l?l?l?l?l, using attack mode 3 (-a 3), so something like: [hashcat executable] -m 2500 -a 3 myfile.hccap ?l?l?l?l?l?l?l?l

Interesting find. Since this sounds like a enhancement or bugfix, you might get better traction by opening a Trac ticket. https://hashcat.net/trac/
