    I really enjoyed the summer course I took in encryption theory, but, even though it was only five years ago, I remember very little. Something about polynomial time versus exponential time….. and from this example, password breaking seems to involve exponential time.

    “To anyone who understands information theory and security and is in an infuriating argument with someone who does not (possibly involving mixed case), I sincerely apologize.”
