Hello. As I'm sure a few of you are aware, the cryptocoin mining game has pretty much come to an end. That said, I'm hesitant to turn around and sell a bunch of essentially free hardware. I'm involved in the infosec sphere already so I figured I should start learning about password cracking. Currently own a mixture of 7950s, 270s, and 270Xs. Setting up a distributed environment looks pretty easy if you just leverage hashtopus. Straight forward interface and deployment (props curlyboi).
All that said, I've trolled around the forums all morning have noticed several places where it's mentioned that CPU cracking can actually be more efficient than GPU for some hash types. Is it even worth have a large GPU cluster running on subpar CPUs and RAM? Rigs don't have any harddrives either, just USB2.0s with an Ubuntu distro. Would that end up being a large bottleneck?
I've also run through all the tutorials and it's become very apparent that rule tuning skill means tons more than hardware available. I can't seem to find any tutorials walking through the thought process of generating passwords from sets of known plaintexts. Any links or references in regards to that would be greatly appreciated.
