Two-choice hashing
WebAlthough it is not possible to "decrypt" password hashes to obtain the original passwords, it is possible to "crack" the hashes in some circumstances. The basic steps are: Select a password you think the victim has chosen (e.g. password1!) Calculate the hash. Compare the hash you calculated to the hash of the victim. WebDec 4, 2014 · 1.

WebSecond-Choice Hashing Suppose that we distribute n balls into Θ(n) bins using the following strategy: For each ball, choose two bins totally at random. Put the ball into the bin with fewer balls in it; tiebreak randomly. Theorem: The expected value of the maximum number of balls in any urn is Θ(log log n).
