Problem with ImageJ list archive

When I tried the link in the message below using Firefox 3.0.5 (on a Mac) I got an error message:
-------

Secure Connection Failed
list.nih.gov uses an invalid security certificate.
The certificate is not trusted because the issuer certificate has expired.
(Error code: sec_error_expired_issuer_certificate)

* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.
-------
I got the same thing when I tried to get to the list archives from the ImageJ Help menu.

I can't reproduce this with Firefox 3.0.5 on Gentoo Linux.
I see the date of the certificate listed as valid till 6/28/09 - what
date do you see?
Perhaps the date on your computer is incorrect?

Hi Pariksheet,

I see the same date. My computer has the correct date. The error message was
misleading. The fault either lies with Firefox or the web site, or some
buggy plugin or extension I have.

Although that error message says the certificate is expired, another message
said something to the effect that the certificate was not issued by a
recognized authority. I guess the US government is not a recognized
authority to Mozilla!!

I eliminated the error by ignoring the advice in Firefox's warning messages
and allowed an "exception" for the untrusted certificate. But I don't see
any way to "unallow" the certificate, so I can't get back to the way it was.

I remember reading a few months ago that Mozilla decided to increase
security in Firefox 3 by not allowing self-signed encryption certificates.
Is that what list.nih.gov is using for their https encryption?

I just went back to the page, https://list.nih.gov/archives/imagej.html,
which now displays correctly. When I look at the page info for the page
(Menu: Tools->Page Info) I see under the Security tab that for Owner it
reads, "This web site does not supply identity information." When I click on
the "View Certificate" button, it reads at the top of the new window, "Could
not verify this certificate for unknown reasons." It also says in this
window:
"Organization (O) U.S. Government". I guess "Owner" is different than
"Organization". (?!)

Does that help someone understand the source of the problem? I don't
pretend to understand this security certificate stuff.

Harry Parker

Hi Harry,

I had the same problem and solved the same way by adding the exception..

You can delete the certificate in Firefox, if you want: in "Tools|Options" you

select "Advanced", then hit the "View Certificates" button an select the

"Servers" tab. Here you scroll down the list and delete the "list.nih.gov"
certificate. Note, that you have to close and restart Firefox for the deletion
to take effect.
Now, the cause I do not understand either...

The problem is unfortunately not with NIH's certificate; that would easily
be fixed. The problem is with an intermediate certificate issuer that has
an expired certificate of its own. So the chain of trust is broken by
them.
