How I obtained the private key for www.cloudflarechallenge.com
I wasn't first to get the key. Nor was I second, third, or even fourth. I'm probably not even the
10th to get it (ok, looks like I was the 8th.) But I'm happy that I was able to prove to myself
that I too could do it.
First, I have to admit I was a skeptic. Like the handful of other dissenters, I had initially
believed that it would be highly improbable under normal conditions to obtain the private key
through exploiting Heartbleed. So this was my motivation for participating in Cloudflare's
challenge. I had extracted a lot of other things with Heartbleed, but I hadn't actually set out to
extract private keys. So I wanted to see first-hand if it was possible or not.

World's First 8x GTX 980 cudaHashcat Benchmark

This benchmark is outdated!

This benchmark was made with the first beta driver to support GM2xx chips. Unfortunately, it was a half-baked driver that failed to unleash this card's true potential. The production version of the driver resolved all performance issues with this card.

For the latest benchmarks, see https://gist.github.com/epixoip/abd64f1af800013abb1f

This is an older benchmark that I just never posted for some reason.
