What exactly is this showing ?


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?

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


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