'Lo Julian,

On Sat, 14 Dec 2002 16:39:03 +0000 your time, you said:

JBL> One considerable disadvantage is the size overhead of S/MIME messages

I would disagree entirely.

JBL> the  signing  process seems to add 6k onto the message size,

Not  when  I  sign  it  doesn't! 3k tops! So I don't know where you get that
figure from.

JBL> and  whilst this might be worthwhile for business communications, where
JBL> the  identity  of the individual is important, it does not appear to be
JBL> worthwhile on TBUDL.

Oh,  I  see,  so personal identity is inconsequential? <cough> Okay! And you
consider  that TBUDL moderators should decide that PGP should be allowed and
S/MIME not? Umm, that's very interesting indeed :) ...although that would be
very hard to justify as The Bat! supports both, don't you think? And this is
The  Bat!  user discussion list after all, isn't it? Where new users and old
congregate to discuss The Bat! features? <g>

JBL> At  least PGP only adds 1k or so to the message size.

Well  I   think  your message is a little misleading, even if unintentional.
So to clear up any confusion I carried out some tests:

A 629 byte email signed with my S/MIME certificate weighs in at 3,634 bytes.
That's  only a difference of about 3k, and not the 6k you claim to start. Of
course  the same 629 byte file PGP clear-signed weighs in at only 993 bytes,
which  seems to be a very small addition in comparison. *However*, if I then
add  my PGP key block to the mail as well, which is the true comparison that
needs  to  be made, the 629 byte email suddenly weighs in at 3,591 bytes. So
the  real  differences  in  size  overhead  are  not  that great at all. The
mechanism for delivery may be differ - the overall bytes split and delivered
in  two  separate  parts - but the size difference isn't significant at all,
and  of  course  S/MIME will have an advantage in many respects as the email
carries the certificate, unlike PGP, and can be immediately imported without
any further requests.
