If you've paid any attention to tech news over the last few days, you may have heard of a serious vulnerability called Heartbleed
. In a nutshell, this is a vulnerability found in OpenSSL
. What's OpenSSL? It's the program used by many web servers to provide HTTPS access via Transport Layer Security
