And the SHA-3 title goes to .....Keccak

In response to a number of attacks  on SHA , NIST started to look for the successor to SHA-2, figuring that it was likely that it to may fall.  To date that hasn't occurred and SHA-512 still looks strong.  The competition proceeded and was whittled down from 64 candidates over a number of rounds.  Yesterday NIST annouced the winner of the SHA-3 competition Keccak 

Keccak (pronounced catch-ack) was developed by: Guido Bertoni, Joan Daemen, Michaël Peeters and Gilles Van Assche. More details on the actual algorithm can be found here

What does it mean for us?  Well you will start seeing SHA-3 folded into FIPS 180-4. You'll start to see the algorithm becoming available within the various security products that require hashing functions.  Until then and possible still even then you can use SHA-512.
