I have also read http://kestas.kuliukas.com/RainbowTables/

I'm designing a "Login-Simulator" that stores pwd-s in a similar manner. The current implementation will be vulnerable to the above attack. Plz could anyone illustrate (in as simple terms as possible), how to strengthen the rainbow tables against such an attack.

When we say dictionary attack, we don't really mean a real dictionary, do we? My guess is we mean a hacker's dictionary i.e. rainbow tables, right? My point is we're not talking about someone keying different passwords into the login box, we're talking about someone who has full access to your database… >>> More
