Automatic watch winders writes: What a great article, I read all of it then i am satisfied to say that It’s a terse idiom, and if you’re concerned about the performance you must not have a database or anything else that consumes resources orders of magnitude greater. Consider yourself lucky, otherwise don’t optimize at this level unless you really need to. Keep blogging.

Joel Klein writes: Could you say more about how you get 3.25 million hashes/second per core? I've only gotten up to about half that, using Polar SSL's SHA1 code. My questions would be: what hash code did you use (link?), what hardware you're running on, and whether you had any particular optimizations particular to the contest situation.
James Harton writes: My demo code has managed to hit a hamming distance of 35 in six different 12 hour runs. I'm finding it very hard to get any closer though.
antirez writes: @Leah: thanks
antirez writes: @Hatem: "2^106 work, rather than the previously expected 2^160 work". The attack is only theoretical (un?)fortunately.
Hatem Nassrat writes: There are some shortcuts that can shorten that time: http://eprint.iacr.org/2004/304
antirez writes: @notaddicted: I'm not sure we are calculating the same thing, my goal was to compute the probability of two random 160 bit strings to have an hamming distance of *exactly* N.
Leah Silber writes: Looks like you're off to a good start :) Good luck, and thanks for participating!
chupacabra writes: Huh?
notaddicted writes: Assume the xor of your test hash with their desired hash is just 160 random bits. Furthermore, choose a certain number N, and assert: they must be white!! What is the probability that this is true: (0.5 for each bit)^(number of bits you chose). So given 160 random bits, what are the chances of there being atlead N bits set to zero? (0.5^N)*(ways to choose N from 160). (0.5^N)*(160!/(N!*(160-N)!)). define d = 160 - N 0.5^(160-d)*(160!/((160-d)!*d!)) So I think that you are miscalculating by a bit, that is why & how.
