What is your point exactly? How secure are Verisign, Thawte or
anyone elses servers outside of them just stating "We take X
Precautions". Look at just about all of the top companies,
Microsoft, Sun, Yahoo, Citibank. They've all been hit at some point
because "X" wasn't secure. Right now I could register at
Comodogroup.com for a free signing cert for email. It means
nothing. Servers storing keys mean little since there is no
authority body to verify the validity of a security claim. So your
point is moot.

When I get the GnuPG distribution from the non-secure
http://gnupg.org (or a
https://gnupg.org with a CAcert.org certificate) I get a
distribution signed by
Werner Koch's key issued one day after the previous signing key
expired
2006-01-01.

The previous expired GnuPG signing key has 160 signatures on the
MIT keyserver.

The new key is signed by Werner Koch's own certification key, and
that's it.

How secure is that certification key?  When I finger
wk () g10code com (another
insecure protocol) I get a keyblock.  Above the keyblock is some
text which
includes this sentence:

   "The primary key is stored at a more or less secure place and
only used on a
    spare laptop which is not connected to any network."

Can anyone estimate the incredible value of the communications and

storage
relying on software signed by that one guy with a "spare laptop in

a more or
less secure place"?

One human being, vulnerable, fallible.  Can he be bought,
blackmailed, coerced?
Hit by a bus?

Can this situation be improved?  I say yes.

Maybe your company has never funded volunteer developers.  Maybe
you asked, and
found you don't do "donations."  Maybe you are just a single-
person consulting
business.

Before last year, I had never paid anyone for all this great free
beer.

But last year I landed a contract that included the need to do
secure code
distribution automatically.  I could never have done it without
calling OpenSSL
libraries.  So, I used paypal to pay one of the lead developers of

OpenSSL to do
a code review.  We easily settled on a contract amount that gave
me a great code
review.  It was well worth it.  Fully tax deductible for me as a
business expense.

But the community got something too.

As mutually agreed ahead of time, the developer got paid more than

his straight
regular consulting rate.  Now he could have kept that as a fat
contract, and
moved on.  But from his perspective, he covered his costs, and
then looked at
the "extra" as compensation for general OpenSSL improvements to
benefit the
whole community.

This may be a way you can convince your company to fund volunteer
developers
too.  If a couple of users a week did that, wouldn't Werner Koch
and colleagues
put some effort towards making stronger weakest links?  Wouldn't
all of us benefit?

Now back to this weakest link.  Does Werner Koch and colleagues
have a Paypal
account or other verified way of receiving electronic payments
easily?
