I have read that SHA-2 is currently unbroken due to the amount of resources and time it would take to crack the hashing, but if we have the step by step algorithm, why can we not just do the steps backwards?
In: Technology
These simplified responses are nice, in that they show why a hash can’t go backwards.
But when you put a password into the website, they compare the hash of your password, to the hash of what you typed. They don’t even need to keep your password saved, they could just keep your hash.
So, the result of the hash isn’t going to be something simple like 42, or something like that, like the one guy explained. If that were true, lots of passwords, would have that same hash. A hash usually results in some crazy 32 or more character random string of letters and numbers which is even more unique than the password you actually entered.
