> Firstly, examples are not proofs "in the sciences" unless they are counterexamples
Yeah, but effectively that's what Your Mother was asking for, a counterexample for the thesis that multidimensional hashes are safe. Hence a "proof" according to you. ;)
updateto elaborate more: every example proofs something, but not every proof needs an example. Or in formal notation: Example => Proof So of course YM's "aka" is not correct in mathematics. But in IT it's important to see how likely a problem is, because nothing is without risk. For instance the same problem might be easily solved with multidimensional keys, where hashes of hashes have a higher risk to run out of space or to be vulnerable of bugs because of higher algorithmic complexity.
