So I did the math quick, but say you had 256GB of ram, and the key was in there somewhere (pretending it’s nicely lined up in some known endian and format), assuming you can visually cut 50% of RAM out by excluding areas the key definitely isn’t in (we know they key doesn’t have 4 repeating chars or is even 1/4 all zero), if you just cycle through each keysize, you need to be in the 10,000 guesses per second to spend less than a year on it. I have no idea the keysize or speed that is practical. But it’s hardly impossible to just dictionary attack using your old RAM as the “list”.
