That's true, but the old compromised key is as good as gone, and whatever it was encrypting can be assumed to be as clear as plaintext. And with the new key, newly encrypted data won't be readable by someone holding the old key, at least. Or are you suggesting something else?

With KDF, do you mean to diffuse/confuse something like "3333" to "x9rn329m43x982ynxy4"?

Ah, good to know that truecrypt uses that. I guess if Y gets compromised then I'll have to make functionality that handles changing of Y as well then.
