When using hashcat, it will run as fast as hashcat&#x27;s dictionary mode. Since we are being cute with named pipes, hashcat thinks its reading a dictionary. There is a caching problem with hashcat though, that is why I set the segment size to 1, so that it can update siga&#x27;s gene pool as often as possible. I am optimistic that there might be a solution to that so that we can leverage hashcat to its full potential.<p>It might be interesting to note that the older versions of hashcat seems to have supported reading candidate passwords straight from stdin. I have not played with that yet, but I suspect it might work a bit better.
