I should add that Security::hash() does not use the salt unless you tell it to,
by passing true in the third parameter. The Auth component does pass true in
the third parameter, so if you want to write code today that will store
passwords in the database that will be compatible with the Auth component when
you switch to it later, you should hash with:
Security::hash($this->data['User']['password'], null, true)
