Does it make a difference against birthday attacks if the algorithm that I am using is 512 bit hashing?

  • $\begingroup$ Hint: my Birthday problem for cryptographic hashing, 101 discusses the probability $p_n$ of a collision after hashing $n$ values among $k=2^b$ with an ideal $b$-bit is hash. This answer concludes that $n\approx2^{92}$ is achievable, with a lots of money. Do the math and decide if $b=256$ or $b=512$ "makes a difference" for you. $\endgroup$ – fgrieu Aug 8 '20 at 11:08
