The pseudo-random data is generated by node.js Crypto module. This is a good thing, because for example: most random number generator are based on time, and if you know when the number was generated, there's a good chance that you can also know what is it (or predict a future generation). In this case, the randomness comes from "noise" gathered from various hardware events, such as a hard drive working or a mouse moving.
