I know that brute forcing a password is hard. I'm not stating the opposite. But
brute forcing a 2048 bit key is not 2 times slower, it's 2398748237489237489
times slower. And you don't need a password for a key! I think that's the right
time to end this conversation, it won't lead to anything good.
