<p>Não sei se todos os leitores sabem, porém, o NIST esta fazendo um campeonato para promover um novo algoritmo de hash para incorporar o padrão SHA-3 e já temos algumas submissões de algoritmos de hash, para ser mais exato, 64 submissões ate o presente momento, sendo que algumas das submissões podem ser encontradas <a href="http://ehash.iaik.tugraz.at/index.php/The_SHA-3_Zoo">aqui</a>.</p>
<p>Bizarro isso, em 2 papers/prototipos postados para o novo padrão SHA-3, 2 já foram quebrados&#8230; isso mesmo!! Colisões já foram encontradas&#8230; no Sgàil e no WaMM e o mais engraçado é que no caso do Sgàil, foi o próprio autor que conseguiu detectar a colisão no hash.</p>
<p>Seguem os links para quem estiver interessado em mais detalhes:</p>
<p><a href="http://web.mit.edu/dwilson/www/hash/wamm.html">WaMM Collision</a> e <a href="http://www.allicient.co.uk/2008/11/05/aww-psh/">Sgàil Collision</a> e as respectivas propostas do <a href="http://washburnresearch.org/cryptography/index.htm">WaMM</a> e do <a href="http://www.allicient.co.uk/files/sgail/">Sgàil</a>.</p>
<p>Para quem curte, vale a pena dar uma olhada nas propostas, até mesmo nas que já foram quebradas e em seus protótipos de implementação.</p>
<p>Ate a próxima&#8230; </p>
