Although part of the same series of standards, SHA-3 is internally quite different from the MD5-like structure of SHA-1 and SHA-2.<br><br>SHA-3 is a subset of the broader cryptographic primitive family Keccak designed by Guido Bertoni, Joan Daemen, Micha\xebl Peeters, and Gilles Van Assche, building upon RadioGat\xfan.";
