A gentle reminder
The laptop I’m writing this on has a quad core processor, eight gigabytes of RAM, and chomps integers 64 bits at a time. It is faster in every respect than every computer I’ve used for work or personal use before. My point is not to brag, but to state the obvious – computers get faster every day.
As a result, computer programs get faster platforms to run on, which means that the password that is eight characters long and has been in your regular rotation for five years now has seen computer power increase more than eightfold. If it was used at a website that has had a user account compromisation in that time, you can safely bet that it has been cracked.
