Random vs. Urandom

“You keep using that word. I don’t think that word means what you think it means.”

I’ve been told for most of my professional life that /dev/random was “better” than /dev/urandom, that one was inherently more secure and sophisticated than the other. I bought it, because it made sense based upon the little I know about cryptography. And there’s the rub. Most of us aren’t experts in the field. This cool little article delves into some good explanations of what is meant by “random” and why it matters. It may turn some of your preciously-held notions upside down, but that’s okay. The day we stop learning is the day we start dying.

Be seeing you!
