Tf is a zero bit and how is it distinct from a zero bit?
- Retr0id 3y agoI'm not quite sure what you're asking here but note that 521 != 512, and the former is not a typo.
- cozzyd 3y agoPlot twist: The choice of 521 is adversarial specifically to exploit PuTTY without being easily noticed. (Ok I get that 2^521-1 is a mersenne prime).
- asddubs 3y agomaybe 2^521-1 being a mersenne prime is adversarial
- tankenmate 3y agoonly in base 10 :)
- asddubs 3y agoI considered making that joke, that the established common base was picked adversarially to have 521 and 512 be confusingly similar but couldn't find a non convoluted way of expressing that without implying primes change with base
- gpvos 3y agoA zero bit is not a cryptographically random bit.
- dspillett 3y agoHere it is the difference between a bit that is part of a cryptographically-safe random number and just happens to be zero, but had equal chance of being one, and a bit that is zero every time because of the way the numbers are being generated.
