> In general, hashed password storage is a tough game to win in an absolute sense. So, we are effectively left with slowing the attacker down to the point that it isn't worth their while.
And? Public key cryptography is impossible in an absolute sense, because there are algorithms that compute the private key given the public key. In fact, we have a good definition of "perfect secrecy", but the only cryptosystems that meet that definition must have keys that are as long as the message, which is impractical. Slowing the adversary down is how practical cryptography works.
