We calculate the salted hash d of the password p and the salt s using the
hash-function H like this:
d = H( p + s ) + s
This will have the affect that d != H( p + s' ) + s' (only if s != s') but
will not protect us against a dictionary attack
since we can easily precompute H( w_i ) where w_i is the ith word of our
dictionary and then just have to validate d == H( H( w_i ) + s ) !?!
