Agreed. Before we start looking for stronger encryption, let's look at
whether we need it. Or at least, we should consider what benefits it
This is why it is so important to bring out the v3 clients. There is not
a lot we are proving by attempting to challenge RC5-64, other than that
the algorithm is secure enough that it takes 20,000 computers over 5 years
to break it. I would much rather my spare cycles be used to search for
prime numbers or extraterrestrial life and prove scientists and
mathematicians right; instead of breaking a code to prove that some
government policy is wrong. -Nathan
