Understood. As far as use of hashcat itself is concerned, you're not doing anything wrong.  And your driver looks current. If you're working from a clean setup as described here (https://hashcat.n...

It sounds like you're doing a lot of work to create word lists with a lot of permutations up front, and storing them. But hashcat has features that make this less necessary. In brute force attacks,...

Post: RE: PeopleSoft with salt

The salt is intrinsic to the hash. The only way to rework the salts would be if you already had the plain text password.

Interesting - I'd totally missed the 1070 Ti as even being an upcoming thing! Eyeballing the specs and the list price, a used 1080 FE would probably still be a better deal?
