weak encryption

[dave madden <dhm@mersenne.com>]

I've been wondering whether weak encryption is, in fact, worse than no
encryption.  Certainly any particular message would fall easily, but
would it still be possible to do bulk traffic scanning if every
message was encrypted with some 40-bit algorithm?  At the very least,
messages that now stick out by virtue of the fact that they're
encrypted should blend in better.  Would you still be able to pick out
the interesting targets if everything was encrypted?
