The center exists, indeed. That's about the point at which reality

While I agree with Phil, there's one thing here which perhaps could
use some clarification:
of physics and information theory for believing that not only is it
computationally infeasible now for us to mount any kind of realistic
attack upon SHA512, but it will forever remain computationally
As for SHA512 being under threat? That is simply ludicrous.
As a quick Fermi estimate --
Brute-forcing a preimage collision in SHA-512 takes 10**153 operations
(2**511).
Each attempt requires erasing 1024 bits of information (512 bits of
input buffer and 512 of output buffer). That's

Breaking RSA-1024 is considered equivalent to an attack of complexity
