It can be cracked - but not reversed. By that I mean that someone can brute force guess at the password and possibly get it right. Given enough resources, it might even be possible to build a database of passwords and their corresponding hashes. I believe IBM holds the patent for that very concept.
It is even possible to intercept the password by a man-in-the-middle attack or by some other social engineering method.
However, there is no mathematical way to take a hash and apply a program to that and end up with the original text. Thus, technically, it can not be reversed.
How did that work out for them, hmmm?
You don’t need the keys to the toy box if you can take the back off with a Phillips head screwdriver.
