The method you purpose is less secure as humans often use low entropy passwords even when you ask them not to. If you are building a system only for humans that use high entropy passwords (are you really willing to bet the farm on that just to save a couple clock cycles) or other machines it might work but I also see no benefit to that approach so you might as well just bcrypt it and call it a day anyway.

I proposed no method. I simply made the statement that typical cryptographic hash functions are optimal (and better than the alternatives) for high entropy passwords. I said nothing regarding low-entropy passwords.

- less primitives

- faster

- less memory usage

- no concern regarding cycles
