FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

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.

Installing SSHPASS

SSHPass is a tiny utility, which allows you to provide the ssh password without using the prompt. This will very helpful for scripting. SSHPass is not good to use in multi-user environment. If you use SSHPass on your development machine, it don't do anything evil.

Installing on Ubuntu

apt-get install sshpass

Installing on OS X
