  • That assumes that an adversary has control of the browser

    No it doesn’t, if they intercept an encrypted password over HTTPS they can resend the request from their own browser to get access to your account

    The big reason you don’t want to send passwords over https is that some organizations have custom certs setup

    What is the problem with that? The password is secure and only shared between you and the site you are intending to communicate with. Even if you sent an encrypted password, they wrote the client side code used to generate it, so they can revert it back to its plaintext state server side anyways

    It is better to just not send the password at all.

    How would you verify it then?

    If not sending plaintext passwords was best practice then why do no sites follow this? You are literally posting to a site (Lemmy) that sends plaintext passwords in its request bodies to log-in












  • We are talking about RSA though, so there is a fixed character length and it isn’t meant to be remembered because your private key is stored on disk.

    Yes the word method is better than a random character password when length is unbounded, but creating secure and memorable passwords is a bit of an oxymoron in today’s date and age - if you are relying on remembering your passwords that likely means you are reusing at least some of them, which is arguably one of the worst things you can do.


  • Words are the least secure way to generate a password of a given length because you are limiting your character set to 26, and character N gives you information about the character at position N+1

    The most secure way to generate a password is to uniformly pick bytes from the entire character set using a suitable form of entropy

    Edit: for the dozens of people still feeling the need to reply to me: RSA keys are fixed length, and you don’t need to memorize them. Using a dictionary of words to create your own RSA key is intentionally kneecapping the security of the key.



  • A server produces an amount of heat equivalent to it’s wattage.

    A 500W server rack will produce 1/3rd the amount of heat as a 1500W space heater. If your rack draws 100W at idle, than that’s how much heat it produces. So if it’s cold outside you could spin up folding at home or some other thing to burn excess CPU cycles

    As long as your server is inside your house it is offsetting the amount of heat your HVAC system needs to produce - granted it is also greatly increasing the amount of work your AC needs to do in the summer

    There is a cricket farm in Quebec that heats it’s enclosures with Bitcoin mining rigs.
