hash cracking on SBCs - DerpUP - 03-31-2019

My favorite thing about mdxfind is it's ability to run on SBCs, it doesn't provide the most power but for hashes like bcrypt or when you have a high value hash you're about to give up on just run it through mdxfind and check on it a month later. The vast majority use less than 10w under full load so they're ideal long term passive cracking attacks without tying up your main workstations. 

I'm going to be trying out a few different brands to see how they compare and thought i'd share some quick benchmarks. 

First up is the le potato by libre computer:
