		<description><![CDATA[NIST has selected five SHA-3 candidate algorithms to advance to the third (and final) round: BLAKE, Grøstl, JH, Keccak, Skein. Selection was announced during December 2010. What do you think, which algorithm will win competition and become new SHA-3 standard? You can vote in poll on this blog (right upper corner).
Here is citation for NIST announcement of 3rd (final) round candidates selection: <a href="http://www.conwex.info/blog/index.php/2011/01/04/nist-has-selected-the-third-final-round-candidates-of-the-sha-3-competition/">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>
