  It's Wordle but it hashes your guess before applying hints.

  It's a clone of the popular wordle game where you have to guess a word, except here, you have to guess a password but instead of telling you which characters of the password are correct it tells you which characters of the corresponding SHA-256 hash are, which makes this pretty much impossible to solve as the whole point of a hash are that small changes in the input (such as a different character in the password) results in big changes in the hash.

    > pretty much impossible to solve Literal understatement of all time…

      A quantum computer could potentially turn it from impossible to merely nearly impossible.

        how so?

          https://en.wikipedia.org/wiki/Grover%27s_algorithm https://en.wikipedia.org/wiki/Grover%27s_algorithm If it works as believed, it should effectively reduce solving SHA-256 to solving SHA-128. Which is extremely difficult, but theoretically possible.

    You can make a rainbow table of the possible passwords & converge pretty quickly Don't hash passwords. Use pbkdf2 or some better alternative (I suggest pbkdf2 because it's widely implemented)

      > You can make a rainbow table of the possible passwords Can you? Here? 14 letters from an alphabet of around 90 characters?

        There's a certain network getting through quite a few SHA256s, just give it a couple decades
