    You can make a client hash it, but if you don’t reject large inputs to your API a client can send enough data to DOS you anyway.

      And a meteor can hit my server the exact time you send your hash which will DOS you/others as well. What’s your point.

      The thread is talking about what it takes to store passwords. There is not DOS potential in a well designed system. Just because you want to arbitrarily conjure up bullshit doesn’t make that any less true.

      Rejecting large inputs != disallowing users to have large passwords. Why are you attempting to straw-man me here?

        You were saying the input size doesn’t matter because you only store the hash which is always the same size. What I’m saying is that the input size really does matter.

        You absolutely should set upper limits on all input fields because it will be abused if you don’t. Systems should validate their inputs, passwords included

          And I showed you a way that we can make it so it doesn’t matter.

          Force local hash -> Hash/salt what you get. Password can be a million characters long. You’ll only ever get like 128 characters.

          Nothing I talked about said to not validate inputs. Just that we don’t have to limit a persons password selection.
