The importance of randomness in online security

I recently visited the website random.org, which is a free/fee-based generator of random numbers.  It's been around for a long time - since 1998.  It made me revisit the concept of randomness and how oddly hard it is to achieve. Why is randomness important? It's amazing how many things rely…
