&gt; &gt; Do you think keysize is more important than choosing a cipher which<BR>
&gt; &gt; made it further in the AES-contest and therefore using Anubis with<BR>
&gt; &gt; 320bit would be a better choice than AES or Twofish with 256bit?<BR>
I think a 256 bit cipher has 2^256 combinations or 115792089237316195423570985008687907853269984665640564039457584007913129639936<BR>
I think a 320 bit cipher has this many combinations:<BR>

I think the number of particals in the universe is 10^72 to 10^87 (http://www.stormloader.com/ajy/reallife.html).&nbsp; I think both numbers are smaller than 2^256<BR>
