    Just as particle physicists measure everything in energy (eV to be precise…)

    Mass? eV Energy? eV Distance? 1/eV Time? Guess what: 1/eV as well! This also means velocity has unit 1…

    And the worst part: it turns out to be extremely useful!













  • Okay first of all this message is really nicely written to explain multi collision attacks! (I knew some stuff about hashing and collision attacks before but not about multi collision and why that would be really useful here.)

    However, I first thought they were looking for inputs which basically preserve a known state and then generating an alphabet with those kinds of blocks (basically have one for each symbol and up to n additional blocks to “reset” the state to the known value) because that could shrink the size of stored blocks by a lot (I’d imagine).

    But now I am wondering if that’s even possible currently (even with an algorithm as “broken” as MD5 has become now)?



  • Except you already have that update installed, the box is not checked and the entry is still respected, nobody could possibly tell you why because that’s not how it’s supposed to work and everyone else works as stated! And now you have to live with the knowledge that your system is in some unobserved quantum superposition with a critical fix in place which may stop working at any moment for any reason and nobody can tell you how you even managed to get into this situation…
