i'll go with that.
And this is why the PGP folks have their heads up their arses, to use a
colloquialism. There are so many other gaps in the system that there
really is no point in forcing people who don't actually need it to use a
"perfect" but hugely overcomplex system.
To abuse an analogy, this is like an airliner with a dodgy engine, a
drunk First Officer, cracks in the rudder, and a malfunctioning
starboard aileron, returning to the gate... because there weren't
enough "refreshing towelettes".
===========
if one is using pgp on windoze, then i agree with that analogy.
i would also agree that pgp signatures, with 1024+ bit keys is complete
and total overkill *if* it's being used an an anti-spam measure... but if
it's being used for other reasons, and it just so happens to be useful in
bypassing a spam filter, then that's a different story. i think that
conventional asymmetric keys in the 256-512 bit range would be adequate
for the purpose of automatically signing an email, *if* the intended
purpose is to bypass a filter, *not* to prove authorship. HOWEVER, the
more i think about that type of system, the more i like hashcash better.
