Is there a (crypto) explanation somewhere about why TrueCrypt uses a key encrypted with the s+pwd, rather than just the s+pwd?
@rygorous That is not sufficient because it is true of the header as well - so there's no advantage. It has to be _amount_ of plaintext...

@cmuratori@rygorous Ie., the header has (at least) "TRUE" encrypted w/ the s+pwd. So it's about the _amount_ of known plaintext... -
@cmuratori As I said before, *several gigabytes* of known plaintext from a normal OS installation. - Show replies

@cmuratori Actually the header in Truecrypt is encoded with *yet another* key... :) -
@rygorous No, not in any real way. It is encrypted with a value derived directly from the salt (known) and the password (unknown). - Show replies
