But if we switch to clear text lengths (with no >other, deeper, changes to the protocol), it gets a lot more difficult. Why? The length just tells you how much to decrypt in one block, what you put inside it is up to you. At a lower level, the TCP headers already give length information, and if you can deal with that then you can just as easily deal with plaintext lengths. Peter.
