(asciilifeform) asciilifeform: asciilifeform however would like to remind readers that hashes are voodoo, and there is no 'proof of hardness' for collision search for any such algo, nor is likely to be.
(asciilifeform) asciilifeform: hashism is intrinsically voodoo, no one has (or , i suspect, ever will have) any proof that particular hash is 'hard' (i.e. has no better solution than brute force)
(trilema) asciilifeform: and for thread-completeness i gotta point out that 'Until the day Bitcoin mining uses up 50%+1 of all electricity generated on planet Earth, this theoretical avenue remains open, if very theoretical' isn't necessarily guaranteed : there always remains ( because Hashing Is Voodoo (tm) ! ) the possibility of discovering shortcut to the mining process ( we had the 'satcoin' thread; possibly other variations on the theme also )
(trilema) asciilifeform: diana_coman: this part i cannot cure , hashing as it stands is an exercise in voodoo
(trilema) asciilifeform: an oaep (or similar scheme) ciphertron rests on 2 elephants : strength of rsa, and strength of the (voodoo) hash.
(trilema) asciilifeform: hashes are voodoo, there is not a hash of demonstrable strength for the same reason there is not block cipher of same ( they are different sides of same medal, we had thread with elementary proof )
(trilema) asciilifeform: anything else puts a megatonne of weight on one single hash, a titanic reward for finding one single solitary collision, hashes (which are voodoo, in all variants, see friday's thread) are not built to withstand this kind of pressure.
(trilema) asciilifeform: this is discussed publicly even less often than the pseudoscientific nonsense of block and stream ciphers, but: hashes are necessarily voodoo. elementarily, by counting argument (input:output sets are not 1:1).
(trilema) asciilifeform: the unfortunate thing about hashes is that they are every bit the voodoo that block ciphers are.
