  • I said nothing about the OS on the phone, why would you assume that I like Android?

    that’s not what I assumed. I assume that this app would only support the 2 most popular mobile platforms, and that on android, as is tradition with payment related apps, it would refuse to work when it detects that your phone’s software has been changed in any significant way.

    if Swish and BankID could run on an open mobile plattform, I’d be happy with that.

    current trend is to make these apps OWASP compliant, which dictates that all apps should at least be an undecipherable, obfuscated black box, and better even make use of the OS’s integrity checking system, like play integrity on android.

    My point it to separate the main computer from the payment system while still being convenient.

    I am a bit confused as how you missed that…

    I did not miss that. I was commenting on this, why it would be harmful in today’s world.








  • if they say you should die because you wanted to talk with them, they are not nice people. you should avoid them for your own benefit. try to find other people if you can, but I would say being alone even is better on a scale. I was in a similar situation for years. and when I thought it ended, it all came back with other people for another few years. if you are a child in school, locked together with them, mentally prepare yourself that they’ll continue bullying you even if you don’t contact them, and that most teachers won’t care. still, you should try getting help if the madness does not stop.







  • the salt does not need to be encrypted. the point of it is that it makes a generic rainbow table useless, because the crackers need to compute hashes themselves for all passwords.

    as they said, the purpose of hashing is to slow down the crackers, because they need to find the string that produces that hash. a rainbow table cancels that, it makes password lookup for an account almost instantaneous. but a rainbow table is only really useful for unsalted hashes, because for salted hashes a different rainbow table is needed that takes the salt into account.



  • B. E-Health Dataset
    The E-Health dataset [20] contains CSI collected from 118 participants (88 men, 30 women) in a controlled indoor environment measuring 3 m×4 m (Fig 4). The setup consists of a router set in the 5 GHz band at 80 MHz bandwidth as a transmitter, a laptop as receiver and a single-antenna Raspberry Pi 4B with NEXMON firmware for CSI data collection (234 subcarriers). Participants wore a Samsung Galaxy Watch 4 for the ground truth.

    does that mean a passive observer can do all that observations? and that a raspberry pi, with its single average antenna is capable of this?
