Congratulations go to PGP Inc - who was it, guys, don't be shy this
time? - for discovering a new way to futz with secure browsing.

Click on http://www.pgp.com/ and you will see an SSL-protected page
with that cute little padlock next to domain name.  And they managed
that over HTTP, as well!  (This may not be seen in IE version 5 which
doesn't load the padlock unless you add it to favourites, or some
such.)

Whoops!  That padlock is in the wrong place, but who's going to notice?
  It looks pretty bona fide to me, and you know, for half the browsers I
use, I often can't find the darn thing anyway.	This is so good, I just
had to add one to my SSL page (http://iang.org/ssl/ ).	I feel so much
safer now, and it's cheaper than the ones that those snake oil vendors
sell :-)

What does this mean?  It's a bit of a laugh, is all, maybe.  But it
could fool some users, and as Mozilla Foundation recently stated, the
goal is to protect those that don't know how to protect themselves.  Us
techies may laugh, but we'll be laughing on the other side when some
phisher tricks users with the little favicon.

It all puts more pressure on the oh-so-long overdue project to bring
the "secure" back into "secure browsing."  Microsoft have befuddled the
already next-to-invisible security model even further with their
favicon invention, and getting it back under control should really be a
priority.

Putting the CA logo on the chrome now seems inspired - clearly the
padlock is useless.  See countless rants [1] listing the 4 steps needed
and also a new draft paper from Amir Herzberg and Ahmad Gbara [2]
exploring the use of logos on the chrome.
