Good point, current verification of password hashes takes as long as generating the hash. I seem to remember that there was a technique to avoid this, but it wasn't usable for passwords or something. Do you happen to have a pointer for what algorithm has this property?
- tromp 3y agoAsymmetric PoW algorithms, such as Cuckoo Cycle [1] or the poorly named Equihash [2] (which is not a hash function) do not lend themselves to password hashing, since a given problem instance can have 0 or 1 or many solutions.
