Modern computers are not what should you afraid. Modern GPUs are.
And they are incredibly fast in calculation of MD5, SHA-1 and SHA-2.
Modern key-derivation schemes must be RAM-heavy, not CPU-heavy.
And I don't understand, why should we use our home-grown
"strengthening" algorithms instead of "standard" choices: PBKDF2[1],
bcrypt[2] and (my favorite) scrypt[3].
