Why are so many bits necessary? Isn't 128bits technically safe against
brute force? At 256 bits you are pretty much safe from any volume of
computational power that one could fathom within this century. The only
real danger is a new computational model that is nondeterministic or
something crazy like that. I feel like what exists currently (from a
quantity of bits standpoint) is more than sufficient.
