<div></div>
<div><span style="color:#000000;"><strong>Discussion:</strong></span></div>
<div style="padding-left:30px;">According to documentation from Cisco, MD5 is computationally less intensive (though considered less secure) than SHA1; AES (considered more secure) is computationally less intensive than 3/DES. The results confirm this. There is a gain of <strong>50KB/s</strong> when going from <em>esp-md5/esp-des</em> to <em>esp-md5/esp-aes 128</em>. When going from <em>esp-md5/esp-aes</em> to <em>esp-sha/esp-aes</em> there is a decrease in the speed. The slowest speed was achieved when using <em>esp-sha/esp-3des/ah-sha</em>. I would like to note that not all combinations of transform sets were tested.</div>
<div></div>
<div><strong>Conclusion:</strong></div>
<div style="padding-left:30px;">The encryption/hash settings does have an effect on the transfer speed with more computationally intensive settings (SHA1 and 3/DES) having a negative effect on the transfer speed.</div>

<content:encoded><![CDATA[<div class='snap_preview'><p>I was watching an investigative piece on the Kennel Club and the problems that in-breeding has on certain breeds &#8211; all very sad. I&#8217;ll hapilly chuck a stick for a dog &#8211; but little else I&#8217;m afraid &#8211; never had one so it&#8217;s one of lifes pleasures that I&#8217;ve never discovered.</p>
<p>Link? We&#8217;ll it&#8217;s about pedigree you see. We (thats web wise business) are a cross breed &#8211; our pedigree is not pure. Instead its from the world or <a title="software company scotland" href="http://www.ObjectiveAssociates.co.uk" target="_blank">triple des security, self service software </a>and electronic engineering &#8211; and that itself is a pedigree of sorts - as it&#8217;s resulted in a <a title="website devdelopment in Scotland" href="http://www.webwisebusiness.co.uk/Websites/WebsitesScotland/tabid/74/Default.aspx" target="_blank">website development business in Scotland</a> that can really nail usability, reliability and scalability. Whether we are a result of inbreeding &#8211; you&#8217;ll have to make that call yourself.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>El otro día me sorprendí cuando, al recibir la renovación de una de las tarjetas bancarias que caducaba a finales de mes, descubrí que traía integrado el famoso chip <a href="http://es.wikipedia.org/wiki/EMV" target="_blank">EMV</a>, llamado a ser el futuro para estos menesteres.</p>
<p>Ya sabía que estaban renovando poco a poco el sistema, pues -siempre según la entidad bancaria- las tarjetas de crédito renovadas ya llevaban un tiempo incluyéndolo. Pero parece que se están poniendo las pilas, porque ahora todas las tarjetas de débito renovadas lo incluyen también. Y más les vale, porque desde 2005 todo fraude realizado en una transacción sin <a href="http://es.wikipedia.org/wiki/EMV" target="_blank">EMV</a>, es responsabilidad del comercio.</p>
<p>Este nuevo sistema introduce, por fin, la <a href="http://es.wikipedia.org/wiki/Criptograf%C3%ADa" target="_blank">criptografía</a> como nuevo invitado a la fiesta, con los obsoletísimos pero rápidos <a href="http://es.wikipedia.org/wiki/Data_Encryption_Standard" target="_blank">DES</a> y <a href="http://es.wikipedia.org/wiki/Data_Encryption_Standard#Algoritmos_de_reemplazo" target="_blank">3DES</a>, y los archiconocidos <a href="http://es.wikipedia.org/wiki/RSA" target="_blank">RSA</a> y <a href="http://es.wikipedia.org/wiki/SHA" target="_blank">SHA</a>. A ver si, cuando pase el <i>asco y odio</i>, saco un hueco para leer <a href="http://www.emvco.com/" target="_blank">por ahí</a> y enterarme de cómo funciona por dentro el invento.</p>
