Not at all. See below. You give yourself away by starting out this way.

If the client's e-mail is to be secure, yes. But let's be accurate here. Phil
is not, nor has he ever been a cryptologist. He's a programmer who learned a
few things about crypto algorithms and copied existing work. His unique
contribution, if there was a technical one, was in key management. I haven't
studied enough cryptology to know if "web of trust" was copied too.

Now that IS nonsensical because cryptology is a wide and deep art only a small
part of which has to do with mail applications themselves. In contrast, mail
applications to be secure must use encryption. There's some very muddy
thinking going on in your post.

Except for the occasional password protection, databases don't need encryption
to the extent e-mail does.

You miss the point here. And you miss the many worked examples. RSA is selling
lots and lots of toolkits for lots and lots of money for in-line integration
into applications, not for pre- and post-processing. The former is the way to
go; the latter a kludge until something better comes along.

You are losing it. First of all I doubt very much that Phil could do this. If
you look at the development time and staffing for good e-mail applications,
this is simply beyond his capabilites and he's never claimed otherwise. Second
of all, it's clear that you've not checked out the current Communicator mail
module if you call it a "piece of crap". You simply don't know what you're
talking about. Same for Internet Explorer, whose mail module has gotten rave
reviews and the best mail program yet and caused reviewers to switch from
Eudora. It, too has integrated crypto.
