- deathanatos 13y agoAs someone else mentions, this doesn't work, as the birthday problem[1] applies here. You need to ensure collisions won't happen; SHA512 does not to that. (The probability of a collision in 512 bits is near impossible; in 33 bits, much less so.) [1]: http://en.wikipedia.org/wiki/Birthday_problem http://en.wikipedia.org/wiki/Birthday_problem
