This benchmark is outdated!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

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.
You can’t perform that action at this time.
