Yep,

Same goes for the Verisign root certs in Netscape <= 4.04.

Normally it'd be possible to just upgrade the cert files, but
unfortunately it seems that the only way to fix the bug after 1/1/2000
will be to upgrade Netscape to 4.05 or later, as there was a Y2K issue in
the date-handling part of their X509 certificate support for SSL.

There's a really crap FAQ up on Verisign's site which vaguely says this in
the most round-about, spin-laden way possible. Here it is:
http://www.verisign.com/server/cus/rootcert/faq.html : "technical and
practices (sic) considerations dictated that the expiration date be set at
12/31/99"... hmmm, gotcha ;)

As I understand it, this will mean that *any* SSL sites viewed with
Netscape <= 4.04, on all platforms, after 1/1/2000 will pop up a "this
site could not be authenticated" dialog. Sad but true.

I'd say it'd include Thawte certs as well, can't see why not -- unless
Verisign have been issuing certs using UTCTime (which has a 2-digit year
field) and Thawte were using GeneralizedTime (which has a 4-digit year
field).

BTW my recommendation would be to go with Thawte, they're much more
professional, reliable, and helpful than Verisign.
