    3 Reasons Why Encryption is Overrated -- http://bit.ly/EokrT

    When it comes to storage and security, discussions traditionally
    center on encryption. The reason encryption is accepted as a best
    practice rests on the premise that while it's possible to crack
    encrypted information, most malicious hackers don't have access to the
    amount of computer processing power they would need to decrypt
    information.

    This blog talks about reasons that encryption is overrated. Curious
    to hear people's thoughts -- agree? disagree? Full post is here:

    Frankly, with dentistry as expensive as yours, you simply can't afford
    to let The Man stamp his jackboot down on your face, and so it is that
    when faced with the inquiry "did Lee Harvey Oswald act alone?", you find
    yourself thinking: "God, I mean ... do any of us? Like, he had to have
    people, you know? At least an agent and a publicist."

    I disagree with most of it, but I'm just a EE, not a security expert.

    However, I'm fairly certain the "future processing power" argument is
    moot. Encryption systems evolve over time. E.g., we no longer use 32-bit
    keys. And the growth of processing power is so slow that encryption
    systems have ample time to evolve.

    I wouldn't get too worried about current or future processing power
    cracking an encryption algorithm. No, the worries are an algorithmic
    breaktrough (e.g., fast factoring) or quantum computing (and quantum
    computing is no big deal - effectively, it just halves the bit strength).

    To put things in perspective there are (very, very roughly) about 10^80
    atoms in the universe - call it 2^266. AES-256 (a common modern crypto
    algorithm) has a strength (against brute force) of about 2^256. IOW,
    broadly comparable to the number of atoms in the universe (let's not sweat
    a mere 2^10 difference on a "soft" number :-)

    Regards,
