I cannot necessarily tell you what your password is.  However, I can 
determine a string with the same hash value, such that it will work just 
as well as your password.  It might be a 197 character piece of junk, 
but it will still work.

Of course, "I" in this case is a hypothetical me who had read about how 
to actually accomplish this, as opposed to having read about how it is 
possible.
