You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the street to the chemist, but that’s just peanuts to space.” Another quote I found that attempts to explain the how big 128 bit keyspace is. Quote: If you want to exhaustively try out all possible 128-bit keys, you will have to take all of the computers on the Internet, multiple their speed by 1,000, and if they all worked together, it would still take 1,000 times the current age of the universe to try out all possible 128-bit keys in order to break a single encrypted message. If we leave the questionable quantum computers out of the equation, Modern cipher breaks don't come by brute forcing keys. They come about through weaknesses in the cipher, or more likely, in the implementation of that cipher. It is just SO much easier to break into someones house and put a keylogger on their computer than it is to brute force 128bit key space. And it would be one heck of a lot cheaper to just pay them a few million dollars to give you the key. And if you don't have much money, rubber hoses are cheap and in abundant supply. Donald
