Ah! Thanks. That immediately answers the second thing I was wondering about, since 2k RSA keys are still deemed safe (if barely / not for secrets that need to last a long time into the future)
In addition to what GP answered: note that I didn't crack anything. I just really did all the 79 trillion sequential computation needed to find the solution. That's the really need thing: you can encode the problem in a split second and yet decide how many sequential steps are needed to find the solution.
