I’ll be the first to admit that cryptography is not the most exciting topic, but as networking grows, encryption methods must as well. The encryption that was used years ago and thought to be impenetrable at the time is now pretty much a joke. This isn’t because it was bad when it was created, but rather the computing power has improved so much that what would have taken years to crack in the past can be done in minutes.
So how do we combat this? It is somewhat of a cat and mouse game. As the encryption methods improve, so does the computing power and the methods to crack it. As I said at the beginning of this post, encryption is not the most exciting topic and reading about it may put some to sleep. Fortunately, some talented folks have put together a very engaging video that talks about this topic and Cisco’s approach. Warning!!! This is not your typical tech video, it is actually fun to watch.
