Apr 27, 2016  Now imagine how many combinations there must be for a 256-bit key yes basically 2 256 possible combinations and don’t forget that even going from a 128-bit key to a 129-bit key would not just double the combinations, it would increase it exponentially! In summary if you’re going for key size, a 128-bit key would be more than enough and a.
