What is Heartbleed? A Simple Explanation.

The Heartbleed bug is the trending topic online this week and I hope to consolidate some resources and explain what the issue is.

This strays from the general theme of technology on the blog so far, but is one of my interests so I hope that you, Reader, find it interesting too.
