The "extra" bits come from the RNG ---for every plaintext bit you send, you're consuming a random bit too. There is also the benefit that the adversary has to find a backdoor in *two* different block ciphers. That is why the rather different IDEA (tm) and Blowfish algorithms are suggested for implementation. --- "We will be obliged to take action ourselves" -Gore on privacy
