  • You’re describing the best case scenario for the person wishing to protect their password, where the Planck Cruncher guesses the password on the very last possible combination, taking 100 years to get there.

    The Planck Cruncher might guess the password correctly on the first try, or it might guess correctly on the last possible combination in 100 years.

    What we really want to measure are the odds of a random guess being correct.

    The most “realistic” scenario is the Planck Cruncher guessing correctly somewhere between 0 and 100 years, but you want to adjust the length of the password to be secure against a powerful attack during the realistic life of whatever system you’re trying to protect.

    On average, assuming the rate of password testing is constant, it’ll take the Planck Cruncher 50 years to guess the 121 character password.

    And that assumes the password never changes.

    If the password is changed while the Planck Cruncher is doing its thing, and it changes to something that the PC has already guessed and tested negative, the PC is screwed.

    Hint: Change your password regularly. edit: The user should change their password regularly during the attack.

    Each password change reduces the risk of a lucky guess by that many years of PC attack.

    I disagree somewhat.

    A lot of high tech development comes with a greed motive, e.g. IPO, or getting bought out by a large company seeking to enter the space, e.g. Google buying Android, or Facebook buying Instagram and Oculus.

    And conversely, a lot of open source software are copies of commercially successful products, albeit they only become widely adopted after the originals have entered the enshittified phase of their life.

    Is there a Lemmy without Reddit? Is there a Mastodon without Twitter? Is there LibreOffice without Microsoft Office and decades of commercial word processors and spreadsheets before that? Or OpenOffice becoming enshittified for that matter? Is there qBittorrent without uTorrent enshittified? Is there postgreSQL without IBM’s DB2?

    The exception that I can see is social media and networked services that require active network and server resources, like Facebook YouTube, or even Dropbox and Evernote.

    Okay, The WELL is still around and is arguably the granddaddy of all online services, and has avoided enshittification, but it isn’t really open source.
