Re: 40-bit RC5 crack meaningless??
This would be the same Strassmann who stated in public at Harvard early in
1995 that most remailers were run by intelligence agencies such as the
KGB, then denied saying it when asked for substantiation? And cut it
from his paper?

Having said that, there is some debate about the extent to which in
*intelligence gathering* as opposed to, say, trying to crack a banking
protocol, one can reasonably count on a known plaintext. And much debate
about the processing costs of not having one, especially when one doesn't
know what kind of document is being encrypted (e.g. is it ASCII plaintext?
a spreadsheet? a jpeg? etc.). I think that's his (misdirected) point.
