MessageMaybe for use in e-mail - OCSP is per cert, which means that every
transaction will lead to a separate connect. Maybe good enough for e-mail,
certainly not for say money transactions - you rather update once in a
while, on quiet hours on your internet connection - not as a home user, but
as a corporate admin. Yes with OCSP you have less data per connection, but
you would have far more connections - if people were to use whatever subtype
of PKI in any significant numbers - which fortunately they don't. In
networking it is not just size that matters, also the number of requests.

If you prefer OCSP - why do you use Verisign Class I - not validated? Then I
noticed something not working in my Outlook E Sp1 on win2k: I said to
explicitily NOT trust this certificate and the darn thing refuses to save
this setting. Am Ioverlooking something or did I stumble into another minor
MS Cockup Experience and have disclosed something?

BTW - Thawte is most commonly used to push dialers onto innocent
p0rnsurfers.... Hey, it trusted and safe software, so you really should
install it .... Lets' associate this great product with connection stealers
and p0rnpeddlers of the worst kind. It will really help get it accepted by
the general public, i guess.

If more clients had embraced OCSP, SCVP, CAM or some other form of
certificate validation, the size of the CRL would be irrelevant. An OCSP
request is only 2kb for example.

I don't know about IE, but with Netscape you can import the CRLs and arrange
for automatic updates with the maximum frequency being once per day.

Even if they did, imagine how much network traffic would be required for
verifying every certificate worldwide?

PKI as it is set up at the moment is as useful as the British MOT test. All
it says is that on a given day your identity (or car) was satisfactorily
inspected. The other 364 (or 365) days anything could happen.

The other problem with Authenticode is that certifcates aren't revokable.
Why doesn't IE go back to Thawte to see if the "Browser Plugin" certificate
is still valid?

Sure Richard it is actually loader of dialer program itself - it even
updates itself any time it wants and it does anything it wants. And there
thousands of people who had this bad luck to "use" that kind of software
without properly realising what they are doing.

Concerning that certifitace - stop trusting things which cannot be trusted.
Would be any COmpany/Street text something you can trust? Would it change
any time that company relocates?

It's problem of Microsoft who made this "authenticode" verification so
misguided and people that they even trust to that. Actually one should not
trust to anything that is not personally known to him...

The downloaded ActiveX file can be found at this URL:
http://80.96.118.2/ac/mw/MSN_QTPieJess1.exe

I ran a strings on the file and the control is called:  TIBS Loader module
and the ProgID is LoaderCon.LoaderCon.  I can't find anything on the Web
about this particular ActiveX control, but it wouldn't surprise me that it
is part of some sort adult dialer scheme.  The control appears to be more of
a downloader program and not the adult dialer itself.

My question:  Why can't an Authenticode certificate present the following
information to a user:

   - Company name
   - Street address
   - Phone number
   - Web site URL
   - Contact Email address
   - Company logo
   - Link to a product description page

All this information can be verified when a company applies for a
Authenticode signing tool.  The current scheme is just plain silly as this
MSN scam illustrates.  There is simply no way to verify where a piece of
software is really coming from.

Browser Plugin is ADULT DIALER - it connects via modem to telephone service
and you pay your sexy adventure through your telephone bill. In many cases,
there are adult dialers committing fraud - they redirect your dial-up
internet connection to very expensive number without your knowledge.

You missed the good part.  If you actually go to the "MSN" Web site and
press the "Connect Now" button, the site tries to download some questionable
ActiveX control.  Not to worry however:

   Just press YES in the dialog box when it appears. This operation is
totally safe and certified by Microsoft Authenticode(tm)

The control is signed by "Browser Plugin".  I guess Thawte will give anyone
an Authenticode certificate nowadays.  I wonder who "Browser Plugin" really
is?
