Then the key space is the pass-phrase space. You had included the

salts are normally not encrypted; there's no real point.
how can the passphrase give away the salt when the salt is created by an RND and the pass-phrase is user generated?
Decrypt it, same as the user would, with the pass-phrase.
i know that the maximum keyspace is 2^512, what i don't know if that remains static irrespective the length of the keystream
and i still dont have an answer as to how the KDF would fare against a dictionary attack, not the twofish key proceedure, the actual KDF which i posted for you to peruse
Have you figured out why that is?
